- 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
