WebWhen a program is assembled, the first instruction is inserted at address 0x0040000. The instructions for the program each take 4 bytes, so the assembler keeps an internal counter, and for each instruction it adds 4 to that counter and uses that number for the address of the next instruction. WebThe following is used for MIPS chips. byte — eight bits. word — four bytes, 32 bits. double word — eight bytes, 64 bits. A block of contiguous memory is referred to by the address of its first byte (ie. the byte with the lowest address.) Most MIPS instructions involve a fixed number of bytes.
