Summary of Course Content

  1. Combinational and Sequential Digital Design Boolean algebra, gates. Commonly used MSI circuits such as multiplexers and decoders. Simple arithmetic circuits. Latches and flip-flops. Finite state machine design. Use of simple digital design simulation software to aid in hierarchical system development.
  2. Interrupts and Interconnection hardware Hardware interrupts. Synchronous and asynchronous buses. Bus arbitration.
  3. Memory Types of memory. Decoding of system-level to chip-level addresses. Caches and the memory hierarchy.
  4. Hardware for Support of Operating Systems Hardware support to optimize resource usage, and to implement the abstraction of a separate machine for each user. Design and use of memory-management hardware, either within-CPU or via separate MMU, to support efficient and convenient OS memory allocation.
