| | | | | There are several commonly used RISC-V instruction pairs with 32-bit immediates. Below is an example of loading a 32-bit immediate into a register using lui/addi: lui rd,imm[31:12] addi rd,rd,imm[11:0] Here lui places a (sign-extended) 20-bit immediate into register rd and fills the lowest 12 bits with zeros, and addi adds a sign-extended 12-bit immediate to register rd. | |

| | | One of the things which RPU has done from the start is keep the cpu pipeline very simple. It's a Fetch, Decode, Execute, [Memory], Writeback pipeline, but it does not run pipelined. Some operations really do require multiple cycles to execute, and in this post we figure out how to add this functionality into the CPU | ||
