Integer multiply and divide instructions form the optional M extension. Making multiplication and division optional keeps the base instruction set simple and reduces the size of the smallest RISC-V core. This post includes a brief overview of common RISC-V extensions.| Project F
This RISC-V assembler post begins by examining the RISC-V jump instructions: jal and jalr. Jump instructions are the basis of functions, so we’ll then dig into function calls, the RISC-V ABI, calling convention, and how to use the stack.| Project F
This RISC-V assembler post covers branch and set instructions, such as beq, bltu, bgez, and slt. We’ll also cover the zero register, program counter, condition codes, and multi-word addition.| Project F
This RISC-V assembler post covers load and store instructions, such as lw, sw, and lbu. We also cover memory alignment, addressing modes, and loading symbol addresses.| Project F
This RISC-V assembler post covers shift instructions, such as sll, srl, and srai. I also explain how to use shift instructions to quickly multiply and divide by powers of two.| Project F
This RISC-V assembler post covers bitwise logical instructions, such as and, not, and xori. Bitwise instructions carry out the specified operator on each bit of the sources in turn.| Project F
This series will help you learn and understand 32-bit RISC-V instructions and programming. The first part looks at load immediate, addition, and subtraction. We’ll also cover sign extension and pseudoinstructions.| Project F
