WebLoad-Store Units. Chapter 1 discussed the difference between instructions that access memory ( load s and store s) and instructions that do actual computation (integer instructions, floating-point instructions, etc.). Just like integer instructions are executed in the IUs and floating-point instructions are executed in the FPUs, memory access ... WebSep 8, 2024 · 1. Out of order execution is a microarchitecture detail. The CPU may reorder instructions only when this doesn't change the observable or specified behaviour. Here, this can be achieved in one of two ways: When the CPU issues a speculative memory access but that speculation was wrong, the CPU must roll back the effects of speculative …

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. When LDM and STM instructions are issued to the LSU pipeline, other instructions run concurrently, subject to the requirements of supporting precise exceptions.
