Next: Bug in Datapath Simulator: Up: No Title Previous: Compiling the Microprogram: Microprogramming: Besides the MIPS subset shown in Figure 5.46, you will use microprogramming to add a few new instructions. If minor datapath changes are needed, make them and describe them (both in terms of the datapath picture and the simulation program). Keep the changes to a minimum. The three students should again randomly decide which person must implement which group of new instructions. Of course, only one person can implement each group of instructions. The instructions are fairly obscure and complex 80x86 instructions (maybe added after the 8086 see Intel's documents), and thus you will have to do a little creative work to ``MIPS-ify'' them to have either an R, I, or J format. Carefully document your new MIPS-ified instructions, detailling the machine language as shown on the inside back cover of your textbook, and documenting what the instruction does. You may refer to the Intel documentation to help explain your instruction. BOUND, BSR

Microprogramming What is microprogramming ? Microinstructions specify all the control signals for the datapath, plus the ability to conditionally decide which microinstruction should be executed next. As the name microprogramming suggests, once the datapath and memory for the microinstructions are designed, control becomes essentially a programming task; that is, the task of writing an interpreter for the instruction set. Wilkes and Stringer first described the concepts of microprogramming in 1953. In the late 50's IBM and others developed the technology for it and introduced microprogrammed control in 1964 with its System/360 computer family. Since then, microprogrammed control units have seen widespread use for several reasons: Instruction-set designers can easily implement complex instructions using them. The cost of microprogramming is far less than the cost of implementing a conventional hardwired control unit. It is easy to add new instructions or modify existing ones (to improve performance or correct an error) when instructions are microprogrammed. Complex operations, such as those required for bootstrap loading, error recovery, and system reconfiguration after a failure, generally require microprogramming, so microprogramming-type memory is present in most computer systems for reasons other than for complex instructions.

Control About Microprogramming Microprogramming is a technique for simplifying the design of a microprocessor. The easiest way to implement control is to make use of a finite state machine. The usual way of specifying a state machine is to draw a state transition diagram. Unfortunately, a microprocessor (especially a CISC) has far to many machine states to allow this to be viable, so another technique for specifying control has been developed. This technique involves writing the steps required to implement an instruction in a way that is similar to writing in assembly language. These steps are called microinstructions and one is executed per clock cycle and corresponds to a machine state in the finite state machine. A microinstruction, like its assembly language equivalent, is divided into fields . Each field controls a certain aspect of the datapath, such as the ALU or the register file. A field can take one of many different values, depending on the datapath. The value of the field determines which control lines are asserted when the microinstruction is executed. A microinstruction also has fields containing sequencing information. The ways of specifying sequencing varies from microprocessor to microprocessor. The method I have used is as follows: microinstructions are executed sequentially unless there is explicit sequencing information. Control can jump an explicit microaddress using a

An outline of this method was given by one of us [Wilkes, 1951a] at the Conference on Automatic Calculating Machines at the University of Manchester in July 1951. The operation called for by a single machine order can be broken down into a sequence of more elementary operations; for example, shifting a number in the accumulator one place to the right may involve, first, a transfer of the number to an auxiliary shifting register, and secondly, the transfer of the number back to the accumulator along an oblique path. These elementary operations will be referred to as micro-operations. Basic machine operations, such as addition, subtraction, multiplication, etc., are thought of as being made up of a micro-programme of micro-operations, each micro-operation being called for by a micro-order. The process of writing a micro-programme for a machine order is very similar to that of writing a programme for the whole calculation in terms of machine orders. For the method to be applicable it is necessary that the machine should contain a suitable permanent rapid-access storage device in which the micro-programme can be held-a diode matrix is proposed in the case of the machine discussed as an example below-and that means should be provided for executing the micro-orders one after the other. It is also necessary that provision should be made for conditional micro-orders which play a role in micro-programming similar to that played by conditional orders in ordinary programming.

A microprogram is a program consisting of microcode that controls the different parts of a computer's central processing unit ( CPU ). The memory in which it resides is called a control store . It is the modern form of the logic of a computer's control unit Before 1955, the control logic for central processing units was designed by ad hoc methods. One of the simplest was to use rings of flip-flops to sequence the computer's control logic. In Maurice Wilkes had a fundamental insight. He realized that if one takes the control signals for a computer, one could understand them as being played much like a player piano roll. That is, they are controlled by a sequence of very wide words constructed of bits.
