Computer Architecture Lecture 2: Fundamental Concepts and ISA

  • Moore's Law
  • Reliability
  • Memory Wall
  • Programmability Wall
  • Design complexity
  • Power/energy constraints
  • Programmability Wall
  • Tradeoffs
  • Three key components of computing: Computation, communication, storage (memory)
  • von Neumann model of computation
  • Stored program
  • Instruction pointer
  • Sequential instruction processing
  • Data flow model of computation
  • Precise state
  • Barrier synchronization
  • Relational and conditional operations
  • Control versus data-driven execution
  • Instruction set architecture
  • Microarchitecture
  • The Connection Machine
  • Bit serial, ripple carry, carry lookahead adder
  • High-level overview of hardware exposure (we'll go into these in more detail in future lectures): pipelining, out-of-order, memory access scheduling, speculative execution, superscalar processing, clock gating, caching, prefetching, voltage/frequency scaling, error correction
  • Very Large Instruction Word (VLIW) processors
  • Design points: Cost, performance, maximum power consumption, energy consumption, availability, reliability and correctness, time to market

 

 Pipelined instruction execution: Intel 80486 uarch

 Multiple instructions at a time: Intel Pentium uarch

 Out-of-order execution: Intel Pentium Pro uarch

 Separate instruction and data caches
