- 1. Processors Ikuru K
- 2. Agenda Overview Hands On
- 3. Note The details are dramatically different from processor
to processor. Try to capture what the essence.
- 4. Physical Look
- 5. Manufacturing Process
- 6. Working Directly with Processors
- 7. Finite State Machine in a Nutshell Next state is a func tion
of current stat e and input, mapp ed by state transfe r function.
Processor is a finit e state machine.
- 8. Processor Implementation
- 9. Main Components RAM Holds instructions and longer term data
Register Storage to do arithmetic/ store pointers ALU circuit that
carries out all arithmetic operations PC program counter that
points to instruction to be d one. BUS Communication between
components (terminal etc)
- 10. Basic Processor Instructions Load to register Write to
address Arithmetic Compare->was result of arithmetic 0? gt 0 ?
lt 0? Jump Modify PC value -> functions are acco mplished using
this.
