WebJul 2, 2024 · Some protocols, like AXI-Stream, deal with this by qualifying the data with a valid flag. In this FIFO read case, not-empty is used as ‘valid’, so the reader doesn’t have to wait. Instead, it launches the read whenever it wants, but doesn’t actually forward the data unless its ‘ready’ and the FIFO ‘valid’ (not-empty) are both true. WebPipeline FIFO Buffer. Decouples two sides of a ready/valid handshake to allow back-to-back transfers without a combinational path between input and output, thus pipelining the path to improve concurrency and/or timing. Any FIFO depth is allowed, not only powers-of-2. The input-to-output latency is 2 cycles. Can function as a Circular Buffer.

WebFIFO. 15.4.27. FIFO. The block models a FIFO memory. DSP Builder writes data through the d input when the write-enable input w is high. After some implementation-specific number of cycles, DSP Builder presents data at output q and the valid output v goes high. DSP Builder holds this data at output q until the read acknowledge input r is set high. Webof the FIFO is immediately presented on the data output lines. By treating the empty signal as!valid and read_en as ready, the read interface of a First-Word Fall-Through FIFO conforms to the ready/valid semantic we have been using in other modules.
