Document Summary
Lec 10 9-16-15 ch2 two key principles of machine. Design / mips instruction set architecture / 32. Regester files / design principles / r format. Instructions are represented by numbers and are therefore indistinguishable from data. Programs are stored in memory that can be modified, which means it can be read from or written to like data. The principles lead to the stored program concept. Computers can inherit already made software as long as they are compatible with an existing instruction set architecture (isa). This causes industry to align around a small number of. Programs can often be shipped as files of binary numbers. 3 types of formats and they are all 32 bits wide. Layout of instruction is called the instruction format simplicity favoring regularity. Mips contains 32 registers, each holding 32 bits. 5 bits are needed to be able to hold all register addresses from the.
