Computer Evolution and Performance Part 11

Intel

• 1971 - 4004
• Microprocessor first
• All components of the CPU is a single chip
• 4 bits
• Following the emergence of 8008 since 1972
• 8 bits
• Microprocessor with special design application
• 1974 - 8080
• Intel is microprocessor with the general usefulness.
  

Increased speed

• Pipelining
• On board cache
• On board L1 & L2 cache
• Branch PREDICTION
• Data-flow analysis
• Speculative execution
  

Comparison of performance

• Increased processor speed.
• Increased memory capacity.
• Speed memory behind than processor speed.
