Document Summary
Components of a computer: key design quality concerns: user, delight, translation, performance, necessary basics: First focus the data path: design a circuit to perform, fetch instructions, locate and read operands, executer instructions, write results into specified location. Cannot compute without telling computer what to do. Execution is much more powerful if the computer can make decisions: dividing a system design into a collection of subsystem design tasks is helpful. Powerful load and store requires use of largest possible range of included constants, implies give all the rest of the bits to them . Use of 32-bit instructions means the above fits in 32 bits. Choosing opcode names : each instruction has an opcode or a name in the form of a specific pattern of a binary string, these patterns will be used by the circuit to control the action of the circuit.
