WebDecouples two sides, *each in their own asynchronous clock domain*, 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 minimum input-to-output latency is 7 cycles when … WebFigure 1. Logic Block Diagram – Synchronous FIFO Architecture (CY7C42x5) 3.1 Reset After power-up, the FIFO must be reset. Resetting the part sets the read and write address pointers to zero, clears the output data register, and sets the status flags to represent an empty device. The device is reset by asserting the RS pin LOW.

WebSep 23, 2024 · The Xilinx FIFO generator used Gray code counters for addressing. Because gray counters have to be designed for mod (2n), the maximum FIFO depth must also be power of 2.

Webencoder/decoders are not required. • Port depths that are not a power of 2 will generate a larger and slower design. The reason is that logic optimization occurs for power-of-2 depths. Thus, if you need a 66 x 8 FIFO, it may be more advantageous to select a FIFO depth of 64 or 128 if area and/or speed are concerns. robert baratheon horned helmetWebTherefore, only when the FIFO depth is a power of 2 can the Gray code go around a circle and return to the initial position with only 1 bit of change, such as 15(1000)----0(0000). … robert baratheon heightWebApr 17, 2024 · 0.
