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. WebLoad Store Unit (LSU) The Load Store Unit (LSU) manages all load and store operations. The load-store pipeline decouples loads and stores from the MAC and ALU pipelines. …

Web2.2 Load store unit The LSU executes all load and store instructions and provides the data transfer interface between the GPRs, FPRs, and the cache/memory subsystem. The LSU calculates effective addresses, performs data alignment, and provides sequencing for load/ store string and multiple instructions. WebLoads and stores of words (32 bit), half words (16 bit) and bytes (8 bit) are supported. Any load or store will stall the ID/EX stage for at least a cycle to await the response (whether that is awaiting load data or a response indicating whether an error has been seen for a store).
