Processor System Architecture
The typical processor system consists of:
1 CPU (central processing unit)
- ALU (arithmetic-logic unit)
- Control Logic
- Registers, etc…
2 Memory
3 Input / Output interfaces
Interconnections between these units:
- Address Bus
- Data Bus
- Control Bus
Bus and CPU
Bus: A shared group of wires used for communicating signals among devices
• address bus: the device and the location within the device that is being accessed
• data bus: the data value being communicated
• control bus: describes the action on the address and data buses
CPU: Core of the processor, where instructions are executed
• High-level language: a = b + c
• Assembly language: add r1 r2 r3
• Machine language: 0001001010111010101
Memory and I/O
Memory: Where instructions (programs) and data are stored
• Organized in arrays of locations (addresses), each storing one byte (8 bits) in general
• A read operation to a particular location always returns the last value stored in that location
I/O devices: Enable system to interact with the world
• Device interface (a.k.a. controller or adapter) hardware connects actual device to bus
• The CPU views the I/O device registers just like memory that can be accessed over the bus. However, I/O registers are connected to external wires, device control logic, etc.
• Reads may not return last value written
• Writes may have side effects
