The high throughput UART to DSP interface (UDIF) maintains UART functionality while integrating dual Transmit (Tx) and Receive (Rx) FIFO buffers that are optimized for more efficient interaction with their respective I/O processors. The portion of the interface design interacting with the DSP, the...
Why does the XPS UARTlite v1.00b not transmit any data during HDL simulation? Solution The status_reg signal in the uartlite_core.vhd is not properly initialized. To work around this problem and maintain the current hardware functionality, perform the following: 1. Open C:\Xilinx\10.1\EDK...
