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. WebFigure 1.

FIFO is an acronym for First In, First Out data organization method. FIFOs are widely used in logic design for buffering, queuing and management of rate, priorities and flow control in data applications. A FIFO consists of a read pointer and a write pointer, pointing to entries in a storage array typically, made of flip-flops. This ...

WebHi, I want to calculate depth of an async fifo, but I am confused how to calculate it. The fifo parameters are as follows: Write Clk Freq = 60 MHz. Read Clk Freq = 100 MHz. Maximum Write Burst Size = 1024. Delay between writes in burst = 4 clk. Read Delay = 2 clk. WebConsumer alternately reads from FIFO1, FIFO2, FIFO1, FIFO2, and so on. A depth of 1 for both FIFOs is enough to avoid deadlocks (and the default depth of 2 optimizes for performance). Producer writes to FIFO1 for N times, then to FIFO2 for N times. Consumer alternately reads from FIFO1, FIFO2, FIFO1, FIFO2, and so on.
