RISC processors are designed to perform a smaller number of computer instructions therefore operate at a higher speed performing multiple instructions per second (MIPS) by removing unneeded instructions and optimizing pathways. WebNov 22, 2007 · asm modulus. Basically you subtract the denominator from the numerator until the denominator is larger than what is left of the numerator. The resulting numerator is the modulus. The shortcut is to shift the denominator to where the next shift will make it larger than the numerator. and subtract this from the numerator. 3 shifts will be 2^3 or ... WebOne way to do this using ARM's ISA would be to first tell the processor to subtract the two numbers; if the difference is zero, then the two numbers must be equal, and the zero flag will be 1. them results in zero, which would set the zero flag.)
