APPROACH
This book provides a foundation in digital design for students in computer
engineering, electrical engineering and computer science courses. It deals
with digital design as an activity in a larger systems design context. Instead
of focusing on gate-level design and aspects of digital design that have
diminishing relevance in a real-world design context, the book concentrates
on modern and evolving knowledge and design skills.
Most modern digital design practice involves design of embedded
systems, using small microcontrollers, larger CPUs/DSPs, or hard or soft
processor cores. Designs involve interfacing the processor or processors
to memory, I/O devices and communications interfaces, and developing
accelerators for operations that are too computationally intensive for processors.
Target technologies include ASICs, FPGAs, PLDs and PCBs. This
is a significant change from earlier design styles, which involved use of
small-scale integrated (SSI) and medium-scale integrated (MSI) circuits.
In such systems, the primary design goal was to minimize gate count or
IC package count. Since processors had lower performance and memories
had limited capacity, a greater proportion of system functionality was
implemented in hardware |
