Microprocessor In a microcomputer , the address of memory locations are binary numbers that identify each memory circuit where a byte is stored. If a microcomputer uses 20-bit address, then numbers of different memory locations are 220 - 1 20 220 220-1 220 - 1 20 220 220-1 ANSWER DOWNLOAD EXAMIANS APP
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 registers takes fewer cycles than that with memory Data processing with memory requires more instructions in the program than that with registers Of limited set of instructions for data processing with memory Data processing with registers is easier than 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 Of limited set of instructions for data processing with memory Data processing with registers is easier than with memory ANSWER DOWNLOAD EXAMIANS APP
