Solutions
- Increasing the number of bits in one time
- Create greater DRAM
- Cache
- Cache more complex and is located on the chip
- 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
- I / O devices
- Interconnection structures
