Document Summary

Intro to machine code: now that we have a processor, operations are performed by: Microprocessor without interlocked pipeline stages (mips: type of reduced instruction set computer (risc) architecture, provides a set of simple and fast instructions. The instruction register, decoding each instruction according to. Compiler translates instructions into 32-bit instructions for the opcode in the first 6 bits instruction memory. The control unit sending a sequence of signals to the rest of the. Complex instructions (multiplication) are built out of simple processor, according to the opcode value passed in from the ones by the compiler and assembler: only question remaining: Assembly language: each processor type has its own language for representing 32-bit instructions as user-level code words, ex. C = a + b store a in , b in , c in . In assembly language instruction: add , , . Note: most of the time only one write signal is on. Regdst = 1 (r-type: mips is register-to-register.
