In this thread, I will try to teach you about a RISC-V processor, piece by piece! You can take a look at the image that depicts the instructions and registers of an RV32I (simpelst) and ask questions before we gradually delve into the design. #riscv #twitterSchool 1 
Oh, I forgot about the registers! Registers are memory in the CPU. They range from x0 to x31. A register has 32 bits in RV32I. The content of x0 is always zero, but we'll get to that later. The registers also have other names (on the right). But let's ignore that for now. 2
In RISC-V, there are many extensions and designations, including 64-bit and 128-bit. But we will ignore that and not go into it. However, there is a little sweet brother RV32E, which has only 16 registers instead of 32. Look here, but ignore it for now.
