Computer Evolution and Performance Part 12

Solutions
- Increasing the number of bits in one time

• Create greater DRAM

- Changing the interface DRAM

• Cache

- Reduce frequency access memory

• Cache more complex and is located on the chip

- Improve the bus system

• High speed buses

• Hierarchy of buses

I / O Devices
- The device needs for operation of I / O
- Need Throughput data that is large enough
- Processor can handle this task
- Problems in the transfer of data
- Solution:

• Caching

• Buffering

• High-speed interconnection buses

• More elaborate bus structures

• Multiple-processor configurations

Typical I / O Device Data Rates


The key: balance
- Processor components
- Main memory
