The cache acknowledges the request by +setting ``cpu_got`` to '1'. If the request is not acknowledged (``cpu_got = +'0'``) in the current clock cycle, then the request must be repeated in the +following clock cycle(s) until it is acknowledged, i.e., the pipeline must +stall. + +A cache access is completed when it is acknowledged. A new request can be +issued in the following clock cycle. + +Of course, ``cpu_got`` may be asserted in the same clock cycle where the +request was issued if a read hit occurs. This allows a throughput of one +(read) request per clock cycle, but the drawback is, that ``cpu_got`` has a +high propagation delay. Thus, this output should only control a simple +pipeline enable logic. + +When ``cpu_got`` is asserted for a read access, then the read data will be +available in the following clock cycle. + +Due to the write-through policy, a write will always take several clock +cycles and acknowledged when the data has been issued to the memory. + +..

This allows to distroy the packet after it was written into the FIFO. --- Usually necessary if the packet is checked for bit-errors and should be distroyed --- if so. --- --- License: --- ============================================================================= --- Copyright 2025-2026 The PoC-Library Authors --- --- Licensed under the Apache License, Version 2.0 (the "License"); --- you may not use this file except in compliance with the License. --- You may obtain a copy of the License at --- --- http://www.apache.org/licenses/LICENSE-2.0 --- --- Unless required by applicable law or agreed to in writing, software --- distributed under the License is distributed on an "AS IS" BASIS, --- WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. --- See the License for the specific language governing permissions and --- limitations under the License. --- ============================================================================= - -library IEEE; -use IEEE.std_logic_1164.all; -use IEEE.numeric_std.all; - -use work.utils.all; -use work.vectors.all; -use work.components.all; -use work.axi4.all; -use work.axi4stream.all; -use work.mem.all; - - -entity AXI4Stream_FIFO_tempput is - generic ( - RAM_TYPE : T_RAM_TYPE := RAM_TYPE_OPTIMIZED;--RAM_TYPE_AUTO; - FRAMES : positive := 2; - MAX_PACKET_DEPTH : positive := 8; - USER_IS_DYNAMIC : boolean := true; - NO_META_FIFO : boolean := false; - ESTATE_WR_BITS : natural := 0; -- Empty State Bits - FSTATE_RD_BITS : natural := 0 -- Full State Bits - ); - port ( - Clock : in std_logic; - Reset : in std_logic; - -- IN Port - In_M2S : in T_AXI4Stream_M2S; - In_S2M : out T_AXI4Stream_S2M; - In_Commit : in std_logic; - In_Rollback : in std_logic; - EState_WR : out std_logic_vector(imax(0, ESTATE_WR_BITS-1) downto 0); - -- OUT Port - Out_M2S : out T_AXI4Stream_M2S; - Out_S2M : in T_AXI4Stream_S2M; - FState_RD : out std_logic_vector(imax(0, FSTATE_RD_BITS-1) downto 0) - ); -end entity; - - -architecture rtl of AXI4Stream_FIFO_tempput is - constant USER_BITS : natural := In_M2S.User'length; - constant DATA_BITS : positive := In_M2S.Data'length; - constant KEEP_BITS : positive := In_M2S.Keep'length; - constant DEST_BITS : positive := In_M2S.Dest'length; - constant ID_BITS : positive := In_M2S.ID'length; - - constant INCLUDE_META : boolean := (USER_IS_DYNAMIC) and (USER_BITS > 0); - - type T_WRITER_STATE is (ST_IDLE, ST_FRAME); - type T_READER_STATE is (ST_IDLE, ST_FRAME); - - signal Writer_State : T_WRITER_STATE := ST_IDLE; - signal Writer_NextState : T_WRITER_STATE; - signal Reader_State : T_READER_STATE := ST_IDLE; - signal Reader_NextState : T_READER_STATE; - - constant Data_Pos : natural := 0; - constant Keep_Pos : natural := 1; - constant Last_Pos : natural := 2; - constant User_Pos : natural := 3; - - constant Data_Bits_Vec : T_NATVEC := ( - Keep_Pos => KEEP_BITS, - Data_Pos => DATA_BITS, - Last_Pos => 1, - User_Pos => USER_BITS - ); - - signal DataFIFO_put : std_logic; - signal DataFIFO_DataIn : std_logic_vector(isum(Data_Bits_Vec) -1 downto 0); - signal DataFIFO_Full : std_logic; - signal MetaFIFO_put : std_logic; - signal MetaFIFO_Full : std_logic; - - signal DataFIFO_got : std_logic; - signal DataFIFO_DataOut : std_logic_vector(DataFIFO_DataIn'range); - signal DataFIFO_Valid : std_logic; - - signal In_SOF : std_logic; - signal started : std_logic := '0'; - - --We set the ranges of Out_S2M_i manually to the values from input to force the input and output record to be the same sizes. - signal Out_M2S_i : T_AXI4Stream_M2S(Data(DATA_BITS -1 downto 0), Keep(DATA_BITS /8 -1 downto 0), User(USER_BITS -1 downto 0), ID(ID_BITS-1 downto 0), DEST(DEST_BITS-1 downto 0)); - -begin - assert not NO_META_FIFO report "PoC.AXI4Stream_FIFO_tempput:: NO_META_FIFO is set.

Vice versa for the *_S2M type. --- --- Usage: --- You can use this record type as a normal, unconstrained record. Create signal --- with a constrained subtype and connect it to the desired components. --- To avoid constraining overhead, you can use the generic sized-package: --- package AXI4Full_Sized_32A_64D is --- new work.AXI4Full_Sized --- generic map( --- ADDRESS_BITS => 32, --- DATA_BITS => 64 --- ); --- Then simply use the sized subtypes: --- signal DeMux_M2S : AXI4Full_Sized_32A_64D.Sized_M2S; --- signal DeMux_S2M : AXI4Full_Sized_32A_64D.Sized_S2M; --- --- If multiple components need to be connected, you can also use the predefined --- vector type T_AXI4_BUS_M2S_VECTOR and T_AXI4_BUS_S2M_VECTOR, which --- gives you a vector of AXI4Lite records. This is also available in the generic --- package as Sized_M2S_Vector and Sized_S2M_Vector. --- --- License: --- ============================================================================= --- Copyright 2025-2026 The PoC-Library Authors --- --- Licensed under the Apache License, Version 2.0 (the "License");

The address of the connected +-- subordinates is defined by the BASE_ADDRESS and the corresponding +-- BASE_ADDRESS_MASK. Every transaction not matching any outputs is internally +-- discarted and a decode-error response is generated. +-- Note that this module terminates ID's on the input and genrates new ID's for +-- every output-port. On response reception, the response is forwarded with the +-- original ID to the manager. The number of read and write ID's is defined by +-- NUM_OUTSTANDING_READS and NUM_OUTSTANDING_WRITES, where the ID's from +-- 0 to NUM_OUTSTANDING_* -1 are generated. Every subordinate must support the +-- given number of ID's to work. Leave NUM_OUTSTANDING_* at init value 0 to +-- generate ID's of the full ID-width (2**ID-width). +-- PIPELINE_IN and PIPELINE_OUT provide the settings for input and ouput +-- pipelining stages as a timing relaxantion setting. +-- +-- Example configuration: +-- 3 Subordinates with 512kB each, starting at 0x0008_0000 +-- BASE_ADDRESS => (0 => 32x"x0008_0000", 1 => 32x"x0009_0000", 2 => 32x"x000A_0000") +-- BASE_ADDRESS_MASK => (0 to 2 => 32x"x0007_FFFF") +-- +-- Utilization compared to Xilinx Crossbar (2.1) 1 Slave => 4 Master (32 Addr/Data) +-- | LUT | FF | Comment | +-- | ---- | ---- | ---------------------- | +-- | 294 | 520 | Xilinx Crosbar ( 2 IDs)| +-- | 320 | 540 | Xilinx Crosbar (16 IDs)| +-- | 258 | 62 | 0 Glue ( 2 IDs)| +-- | 823 | 199 | 0 Glue (16 IDs)| +-- +-- License: +-- ============================================================================= +-- Copyright 2025-2026 The PoC-Library Authors +-- +-- Licensed under the Apache License, Version 2.0 (the "License");

The number of read and write ID's is defined by +-- NUM_OUTSTANDING_READS and NUM_OUTSTANDING_WRITES, where the ID's from +-- 0 to NUM_OUTSTANDING_* -1 are generated. +-- The subordinate must support the given number of ID's to work.

For example, --- let's have a pipeline where a load/store instruction is executed in 3 --- stages (after fetching, decoding, ...): --- --- 1. Execute (EX) for address calculation, --- 2. Load/Store 1 (LS1) for the cache access, --- 3. Load/Store 2 (LS2) where the cache returns the read data. --- --- The read data is always returned one cycle after the cache access completes, --- so there is conceptually a pipeline register within this unit. The stage LS2 --- can be merged with a write-back stage if the clock period allows so. --- --- The stage LS1 and thus EX and LS2 must stall, until the cache access is --- completed, i.e., the EX/LS1 pipeline register must hold the cache request --- until it is acknowledged by the cache. This is signaled by ``cpu_got`` as --- described in Section Operation below. The pipeline moves forward (is --- enabled) when:: --- --- pipeline_enable <= (not cpu_req) or cpu_got; --- --- If the pipeline can stall due to other reasons, care must be taken to not --- unintentionally executing the cache access twice or missing the read data. --- --- Of course, the EX/LS1 pipeline register can be omitted and the CPU side --- directly fed by the address caculator. But be aware of the high setup time --- of this unit and high propate time for ``cpu_got``. --- --- This unit supports only one outstanding CPU request. More outstanding --- requests are provided by :ref:`IP:cache_mem`. --- --- --- Configuration --- ************* --- --- +--------------------+-----------------------------------------------------+ --- | Parameter | Description | --- +====================+=====================================================+ --- | REPLACEMENT_POLICY | Replacement policy of embedded cache.

Each memory word --- (and each cache line) consists of MEM_DATA_BITS bits. --- For example if MEM_DATA_BITS=128: --- --- * memory address 0 selects the bits 0..127 in memory, --- * memory address 1 selects the bits 128..256 in memory, and so on. --- --- Cache accesses are always aligned to a CPU word boundary. Each CPU word --- consists of CPU_DATA_BITS bits. For example if CPU_DATA_BITS=32: --- --- * CPU address 0 selects the bits 0.. 31 in memory word 0, --- * CPU address 1 selects the bits 32.. 63 in memory word 0, --- * CPU address 2 selects the bits 64.. 95 in memory word 0, --- * CPU address 3 selects the bits 96..127 in memory word 0, --- * CPU address 4 selects the bits 0.. 31 in memory word 1, --- * CPU address 5 selects the bits 32.. 63 in memory word 1, and so on. --- --- --- Shared and Memory Side Interface --- ++++++++++++++++++++++++++++++++ --- --- A synchronous reset must be applied even on a FPGA. --- --- The memory side interface is documented in detail :ref:`here `. --- --- --- CPU Side Interface --- ++++++++++++++++++ --- --- The CPU (pipeline stage LS1, see above) issues a request by setting --- ``cpu_req``, ``cpu_write``, ``cpu_addr``, ``cpu_wdata`` and ``cpu_wmask`` as --- in the :ref:`INT:PoC.Mem` interface. The cache acknowledges the request by --- setting ``cpu_got`` to '1'. If the request is not acknowledged (``cpu_got = --- '0'``) in the current clock cycle, then the request must be repeated in the --- following clock cycle(s) until it is acknowledged, i.e., the pipeline must --- stall. --- --- A cache access is completed when it is acknowledged. A new request can be --- issued in the following clock cycle. --- --- Of course, ``cpu_got`` may be asserted in the same clock cycle where the --- request was issued if a read hit occurs. This allows a throughput of one --- (read) request per clock cycle, but the drawback is, that ``cpu_got`` has a --- high propagation delay. Thus, this output should only control a simple --- pipeline enable logic. --- --- When ``cpu_got`` is asserted for a read access, then the read data will be --- available in the following clock cycle. --- --- Due to the write-through policy, a write will always take several clock --- cycles and acknowledged when the data has been issued to the memory. --- --- ..

Reset - strobed input to the design --- P .. Pulse - strobed input to the design --- S .. Switch - stateful input to the design --- L .. Light - (bit) output from the design --- D .. Digit - (hex) output from the design --- --- This letter may be followed by a hexadecimal input vector, which triggers --- --- R - a strobe on the corresponding inputs, --- P - a strobe on the corresponding inputs, and --- S - a state toggle of the corresponding inputs. --- --- The input vector is ignored for outputs from the design. --- The command line may contain an arbitrary amount of spaces. --- --- The terminal interface will echo with: --- --- ['] --- --- The and will only be present if, at least, --- a single instance of the addressed resource type is available. --- In particular, the resource characters of lines starting with other than --- the listed resource types will simply be echoed. --- The describes how many bits of the addressed resource are --- available, which may be used to explore the resources using a command line --- with no or a zero input argument. The is typically provided in --- decimal (default) but may be changed to hexadecimal through the generic --- parameter COUNT_DECIMAL. --- The acknowledges the input (R and P) and informs about --- the current state (S, L and D). --- --- Example: --- > L --- L10'21D --- > D --- D8'5E --- > A --- A --- > S --- S6'00 --- > S3A --- S6'3A --- > S 1 --- S6'3B --- > P8 --- P4'8 --- > P --- P4'0 - --- Authors: Thomas B.
