Computer Architecture

**_Computer Architecture _** 1. Using diagrams, describe how the fetch-execute cycle works in a von Neumann computer. In your explanation, you must include at least the operation of : a)the instruction register b)the program counter c)the accumulator or register d)the arithmetic logic unit e)the status register Illustrate the operation by explaining in detail i) how a simple arithmetic calculation (e.g. result=num1*num2) is carried out and ii) how a jump is implemented. 2. Using a complicated arithmetic expression as an example, explain how it needs to be broken into separate parts prior to implementation on a computer and how the computation process is helped by the use of more than one general purpose register. **Marks** You will be awarded marks as follows: Ø Technical content and accuracy (part 1)40% Ø Technical content and accuracy (part 2)20% Ø Presentation 15% Ø Evidence of research25% Up to 10% may be deducted for bad spelling and grammar. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
