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. Web(March 2024) In computer engineering, a load–store unit (LSU) is a specialized execution unit responsible for executing all load and store instructions, generating virtual addresses of load and store operations [1] [2] [3] and loading data from memory or storing it back to memory from registers.
