How does load instruction work?
Load instructions move data from memory to registers.
Store instructions move data from registers to memory.
Move instructions move data from one register to another.
Immediate load instructions move constants, including addresses, to registers..
What does load do in registers?
The operands for all arithmetic and logic operations are contained in registers.
To operate on data in main memory, the data is first copied into registers.
A load operation copies data from main memory into a register.
A store operation copies data from a register into main memory ..
What is a load instruction?
Load instructions move data from memory to registers.
Store instructions move data from registers to memory.
Move instructions move data from one register to another.
Immediate load instructions move constants, including addresses, to registers..
What is load and store operations?
In a load-store architecture, all arithmetic operations get their operands from, and produce results in addressable registers.
Communication between memories and registers requires separate “load” and “store” operations, which may be scheduled in parallel with arithmetic operations if permitted by the instruction set..
What is load in computer architecture?
In computer engineering, a load–store architecture (or a register–register 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)..
What is the difference between load and store in computer architecture?
Data movement instructions can be grouped into loads, stores, moves, and immediate loads.
Load instructions move data from memory to registers.
Store instructions move data from registers to memory..
What is the load store unit of a CPU?
The Load/Store Unit (LSU) is responsible for deciding when to fire memory operations to the memory system.
There are two queues: the Load Queue (LDQ), and the Store Queue (STQ).
Load instructions generate a “uopLD” Micro-Op (UOP).
When issued, “uopLD” calculates the load address and places its result in the LDQ..
What is the purpose of load instruction?
Load instructions move data from memory to registers.
Store instructions move data from registers to memory.
Move instructions move data from one register to another.
Immediate load instructions move constants, including addresses, to registers..
Why is RISC called load-store architecture?
RISC-V is a load-store architecture, meaning three things: (i) Its arithmetic instructions operate only on registers, (ii) Only load and store instructions transfer data to and from memory, and (iii) Data must first be loaded into a register before it can be operated on ”Dec 14, 2022.

- 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. - The load–store unit usually includes a queue which acts as a waiting area for memory instructions, and the unit itself operates independently of other processor units.
Load–store units may also be used in vector processing, and in such cases the term "load–store vector" may be used.
