Last time, I presented a Verilog code for a 16-bit single-cycle MIPS processor. So i have 3 inputs for my register a. So, when this signal is on, it means it is write back stage. That&x27;s probably why he&x27;s implementing his own using an FPGA. This in turn allows for smaller instruction codes. We could also create a function that returns the number of--bits, which could be used everywhere, but that will be shown in a later--example. Using only the required registers, i. The RTL view is totally equivalent, i. It can be described as 3-ported synchronous RAM with R0 hardwired to zero. Shift register VHDL description 1 In this case, each register is declared in the architecture declarative part. In general, a register-based FIFO should be used for small FIFOs (say under 32 words deep) and a Block RAM based FIFO should be used.
