A single-cycle MIPS processor
An instruction set architecture is an interface that defines the hardware
operations which are available to software.
Any instruction set can be implemented in many different ways. Over the
next few weeks well see several pos
MIPS arithmetic
Today well review all the important ideas of arithmetic from CS231.
Unsigned and signed number representations.
Addition and subtraction with twos complement numbers.
Overflow detection.
These issues are important in understanding MIPS
Decoder-based circuits
Today well study decoders, another commonly-used circuit.
This lecture will follow the outline of yesterdays multiplexer lecture.
There are different ways to design and build decoders.
Decoders can be used to implement arbitrary f
Basic circuit design and multiplexers
In the first three lectures we learned all the
fundamentals needed for making circuits.
Truth tables and Boolean expressions
describe functions.
Expressions can be converted to circuits.
Boolean algebra and K-maps
More MIPS instructions
Last time we introduced the MIPS instruction set architecture, with its
three-address instructions and dedicated loads and stores.
Today well go into more detail about the ISA.
Constant values can be embedded in instructions.
