Abstract
A blockRAM based FIFO utilizes the blockRAM components to implement a one-cycle latency read FIFO. This FIFO implementation, while utilizing blockRAM, provides fast clock to out times by registering all data in a register prior to presenting it to the user. Because this implementation transparently registers the data, the user interface remains identical to conventional FIFO implementations, while solving the slow clock-to-out time associated with blockRAM based FIFOs. A blockRAM based zero-cycle latency read FIFO is also described.
