Web10 apr. 2024 · I was confused on how I would go about multiplying two 64 bits with each other in Risc-v assembly. I want to load numbers that are 64 bits, multiply them, and store it back in a variable and print the result. From what I understand you have to load the variables into a register, use mul and mulh to store upper and lower and then store it … WebDivide instructions. SDIV. Signed divide. UDIV. Unsigned divide. There are multiply instructions that operate on 32-bit or 64-bit values and return a result of the same size as the operands. For example, two 64-bit registers can be multiplied to produce a 64-bit result with the MUL instruction. MUL X0, X1, X2 // X0 = X1 * X2.

Web4 apr. 2024 · The simplest version is MUL which multiples two 32-bit registers and stores a 32-bit result into a general-purpose register. As a side effect, it corrupts the HI and LO registers. (This is the only multiplication or division operation that puts the result in a general-purpose register instead of into HI and LO .)

Did you know?

The mul instruction has 2 operands: one is specified and the other one is implicit. When you write mul cx it means something like: ax = ax * cx. Actually it means dx:ax = ax * cx - the high half of the full 32-bit product is always written to dx. dx will be zero for small products where the result "fits" in ax. WebThe semantics are given below: (HI, LO) = Rs * Rt. We know that multiplying the contents of two 32-bit registers will give a 64-bit result. The high 32 bits are placed in a register called HI.The low 32 bits are placed in a register called LO.You only need to read LO if you know your result fits into the Lower 32-bits.. To access the HI and LO registers, which are 2 …
