Dear Forum participants,

I am working on an implementation SPI hardware interface in VIVADO. I have already read a lot of basic information about it.

My plan

The bus is configured as a 3 wire interface as far: clk, data_in and cs ( clock, input data and chip select, respectively). I add two FIFO ( one receives 8 bits and sends to the second one) block and blocks for a bit counter and bit selection. If the second FIFO is full, bit selection block will start a filling with a new 8 bits.

Have I smth missed? What should I add to this realisation?

Does anyone have a reference how SPI could be realised for receive data ?

Try a Google search for "Verilog SPI slave". The first few hits lead to example SPI implementations.
