RTL design techniques of asynchronous FIFO memory blocks with area and power consumption optimizations
Annotation
this paper presents several new asynchronous FIFO designs. While most existing FIFO’s have higher throughput for higher latency, our goal is to achieve very low latency while maintaining good throughput. The designs are implemented as circular arrays of cells connected to common data buses. Data items are not moved around the array once; they are enqueued. Each cell’s input and output behavior is dictated by the flow of two tokens around the ring: one that allows enqueuing data and one that allows dequeuing data. Since the problems were found in gray code's nature, both FIFO architectures repr...
