Microprocessor A good assembly language programmer should use general purpose registers rather than memory in maximum possible ways for data processing. This is because: Data processing with memory requires more instructions in the program than that with registers Data processing with registers is easier than with memory Of limited set of instructions for data processing with memory Data processing with registers takes fewer cycles than that with memory Data processing with memory requires more instructions in the program than that with registers Data processing with registers is easier than with memory Of limited set of instructions for data processing with memory Data processing with registers takes fewer cycles than that with memory ANSWER DOWNLOAD EXAMIANS APP
