Document Summary
The arithematic side of alu: s0 far, we"ve been talking about making devices, such as adders, fundamentally, this side is made of an add/subtractor unit counters and registers, the ultimate goal is to make a microprocessor. A digital device that processes input, can store values and produces output, according to a set of on-board instructions. In addition to data inputs and outputs, this circuit also has: Inputs specifying the operation to perform (similar to sub: deconstructing processor consider them piece by piece, microprocessors. These devices are a combination of the units that we"ve discussed so far: Finite state machines to control the process. Arithematic logic unit (alu) the arithmetic thing : the first microprocessor applications were calculators. Recall the unit on adders and subtractors. Input a and b = data inputs for the operations. Sends b straight through to the adder. Result of addition operation: g = a + b. Result of addition operation: g = a 1.
