No. of lectures: 6
Prerequisite course: Digital Electronics
This course is a prerequisite for the Group Project
(Part IB) and
for VLSI Design (Part II).
Aims
The aims of this course are to introduce the principles and techniques
used in the design of hardware systems. The course examines the
hardware building blocks that are currently available, and discusses
how designs may be partitioned to make best use of these components.
It will be illustrated with case studies that show how a number of
`real-life' hardware systems have been implemented.
Lectures
- Building blocks for digital electronics and HDL.
D-type, clock enable, broadside register, ROM, RAM, ALU,
microprocessor.
- Clocking and synchronous FSM combination.
Finite state machines: Mealy, Moore, composition and pipelining.
Decomposition. Set and hold times, clock skew. FSMs on different
clocks. Asynchronous boundaries. Gated clocks.
- Technology, speed, power, gate delays.
Capacitance, inductance, resistance, speed of light. Model of a gate,
derating of a model with load and temperature. Delay-power
product. Model of a net. Back-annotated net delay. IO pads and PCB
tracks. Modular design, libraries and design partition: Standard
parts, ASICs, PALs and FPGAs. [2 lectures]
- Hardware versus software.
Processor speed, hardware speed, design reuse, full custom versus semi-custom, bit serial logic, microcode, embedded systems,
ROM and processor on the same chip. Design partitioning.
- Further circuit structures and examples.
Objectives
At the end of the course students should
- be able to partition designs into appropriate hardware and
software sub-systems
- know what kinds of component are available to the hardware
designer, and be able to partition designs accordingly
- understand timing issues such as setup and hold times, clock
skew, propagation delays, and clock re-synchronisation
- know techniques for building state state machines that have
different performance / density tradeoffs
