How MIPS load and store instructions?
To get stuff to/from memory and into/out of registers, we have explicit instructions that move data. Load instructions read data from memory and copy it to a register. Store instructions write data from a register to memory. The MIPS R2000 is a load/store architecture.
What does store instruction do?
Stores a word of data from a general-purpose register into a specified location in memory. The stw and st instructions store a word from general-purpose register (GPR) RS into a word of storage addressed by the effective address (EA).
What does store byte do?
The MIPS ―load byte‖ instruction lb transfers one byte of data from main memory to a register. The ―store byte‖ instruction sb transfers the lowest byte of data from a register into main memory. So, to compute with memory-based data, you must: Store that value back to memory if needed.
How is a string stored in MIPS?
asciiz in MIPS, and each character in the string is stored in a byte. In order to obtain a specific character code (decimal) in the MIPS program, I will have to use lb (load byte) instruction, and specify the byte position of the string to get back the character decimal stored in that byte.
How does load and store work?
A load operation copies data from main memory into a register. A store operation copies data from a register into main memory . When a word (4 bytes) is loaded or stored the memory address must be a multiple of four.
What are the MIPS store word and Load Word commands?
While MIPS is considered a Reduced Instruction Set Computer (RISC) it can still be difficult to get familiarized with. Two of the basic operations available to programmers are the Store Word (SW) and Load Word (LW) commands. These commands are used to retrieve (load) and save (store) values from specified memory locations.
What are the basic MIPS operations?

What is the size of a pointer to data in MIPS?
1 Answer 1 ActiveOldestVotes 1 On MIPS, the size of a pointer to your data is .word, usually 32 bits. Furthermore, MIPS requires that your data is aligned to certain addressesdepending on the type (i.e. size) of the data itself.
Is MIPS32 a good language to learn?
MIPS is a great language to learn the basics of assembly programming. The MIPS32 architecture helps expose a RISC set of instructions in a reduced memory setting which helps simplify things further. Basically, one wrangles 32-bit memory addresses during debugging rather than 64-bit addresses.
