RTL and Verilog Testbench of SPI Wishbone Controller


The Serial Peripheral Interface (SPI) bus provides an industry standard interface between microprocessors and other devices as shown in Figure below . This reference design documents a SPI WISHBONE controller designed to provide an interface between a microprocessor with a WISHBONE bus and external SPI devices. In master mode, the SPI controller can be configured for communication with multiple off-chip SPI ports. In slave mode, the SPI supports communications with an off-chip SPI master.
