WebIn a load-store architecture, all arithmetic operations get their operands from, and produce results in addressable registers. Communication between memories and registers … In computer engineering, a load–store architecture is an instruction set architecture that divides instructions into two categories: memory access (load and store between memory and registers) and ALU operations (which only occur between registers). Some RISC architectures such as PowerPC, SPARC, RISC-V, ARM, and MIPS are load–store architectures.
