Signed Numbers,We’ve designed adders that can work with positive numbers. But what about negative numbers? We call systems that can incorporate negative numbers . and consider those that cannot handle negative numbers to be .. The binary system discussed in the previous chapter is more properly called .

Encoding Code,We’re using the computer as the main motivating example throughout our development of digital design, so let’s get to programming!

Sequential Logic Elements,When we write our programs, we take for granted the fact that we can declare a variable x and assign it some value and be assured that it will retain said value until we specify it is to be modified.

Multiplexers and Comparators,Now that we have a register and an adder, we can start building . to implement our instructions. Suppose we have the instruction . which will compute A + R1 and store the result back in A. The circuit in Fig. 12.1 does this for us.

Decoders and Register Files,The multiplexer lets us select one of a number of inputs to pass through to the next device. The . allows us to select one of a number of connected devices to activate in response to an input (the eponymous .). These devices are similar and are often confused by those new to digital design.

Logic Gates,demanded by the equations derived for our logic functions. If our minimal form is ., say, then we need to perform one NOT operation, one two-input OR operation, and two two-input AND operations. We can draw a schematic of the circuit layout required, as seen in Fig. 6.1:
