Demonstrate an understanding of the structure and components of a digital computer

Provide a detailed description of the fundamental CPU components- registers, ALU and CU; describe how data is stored and accessed in RAM; describe a range of storage and IO technologies. Provide a clear account of how data is transferred between the various components of a computer system. Identify the principle components of a computer system and outline their function.

Understand how data can be stored digitally; make use of common units of measurement e.g.KB, MB GB etc; understand and make use of various number systems.

Perform base conversions; perform binary addition using twos complement arithmetic; perform a variety of bitwise operations. Describe the IEEE 754 standard for floating point representation. Understand the various units of data measurement; recognize and understand binary, octal and hexadecimal number systems.

Describe the operation of the standard gates; understand how gates can be combined to produce registers and ALUs and other components of the micro-architecture level.

Describe the function of various micro-architecture components e.g. half and full adders, the ALU, the role of the PSR. Understand and describe in detail the internal structure of at least one micro-architecture component. Identify and understand the operation of the standard logic gates; design simple combinational circuits.

Describe the role of micro-code; understand the relation between the ISA and assembly language levels; understand a variety of assembly language instructions.

Translate selected assembly language instructions into machine code; describe the operation of a variety of more advanced assembly language instructions (e.g. stack operations); distinguish between CISC and RISC architectures; describe the relation between the ISA and micro-code levels. Translate short fragments of a high-level language into assembly language programs; construct ISA level instructions from micro-code instructions Specify the operational semantics of a range of basic assembly language instructions; understand relation between assembly language and machine code.

Analyse the fetch-execute cycle as it applies to a range of assembly language instructions.

Identify and describe in general the sequence of steps involved in the fetch-execute cycle. Provide a detailed trace for specific instructions during the course of the fetch-execute cycle; understand a range of addressing modes; describe how IO is managed. Describe the role of interrupts and how they are dealt with during the course of the fetch-execute cycle; compare different IO schemes.

Recognise system development software.; understand the difference between various kinds of language processors.

Describe in outline the function of various kinds of systems software, Explain how systems software figures in a multi-level view of a computer system. Clearly distinguish different types of language processors and system development tools.
