A badic controller for the UART. It incorporates a -- transmit and receive FIFO (from Max+Plus II s MegaWizard -- plug-in manager). Note that no checking is done to see -- whether the FIFOs are overflowing or not. This strictly -- handles the

一个先进先出的内存，使用一个同步时钟产生各种不同尺寸的高速缓冲-a first-in first out memory, uses a synchronising clock generics allow fifos of different sizes to be instantiated

Shows how to set up a FIFO data queue for sharing data between real-time tasks and user-level applications. The RT task creates two FIFOs, one for commands in from the user process and one for status back to the user process. As declared in

The SC16C752B is a dual Universal Asynchronous Receiver/Transmitter (UART) with 64-byte FIFOs, automatic hardware/software flow control, and data rates up to 5 Mbit/s (3.3 V and 5 V). The SC16C752B offers enhanced features. It has a Transmission
