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. great clips medford oregon online check inWebApr 28, 2024 · The load/store units coalesce 32 individual thread accesses into a minimal number of memory block accesses.
