Week 8 — I/O & storage
Understand the "vocabulary" of a processor, including how instructions are fetched, decoded, and executed. Computer Architecture And Organization John P Hayes Pdf
: Tracks computer development from early mechanical calculators to modern microprocessors. Von Neumann Model Week 8 — I/O & storage Understand the
This is where Hayes famously shines. He contrasts the speed of hardwired control units (used in RISC processors) with the flexibility of microprogrammed control (classic CISC). The text includes micro-operation sequences that make the "magic" of computing feel logical and mechanical. He contrasts the speed of hardwired control units
Focuses on how the CPU interacts with the outside world through buses (PCI, SCSI, USB) and I/O control mechanisms like DMA.
In the late 1960s, a young Irish engineer named John P. Hayes
(McGraw-Hill) remains the standard, focusing on both the "big picture" architecture and the internal "organization" of modern digital computers. Core Topics Covered
