The is a soft Core of a Universal Asynchronous Receiver/Transmitter (UART) functionally identical to the TL16C550A. The D16550 allows serial transmission in two modes: UART mode and FIFO mode. In FIFO mode internal FIFOs are activated allowing 16 bytes (plus 3 bits of error data per byte ...
An interesting technique for doing FIFO design is to perform asynchronous comparisons between the FIFO write and read pointers that are generated in clock domains that are asynchronous to each other. The asynchronous FIFO pointer comparison technique uses fewer synchronization flip-flops to build the ...
