    http://nigelfurness.thornet.co.uk/microprogram.html
    
    Extractions: Microprogramming Simplified Microprogramming is the name applied to a development of the technique of using Read-Only Memory (ROM) or diode matrices for instruction decode in a CPU. The principle is based on binary coding an instruction such that its binary value forms the address of a location in a block of memory built within the CPU. The addressed location contains a hard-wired bit pattern that corresponds to the necessary control signals required to perfom the instruction. Instruction decode then takes place by gating the bit pattern on to the CPU's control bus. Effectively the memory acts as a translation table from Instruction or Order Codes to the required control signals. These control signals then activate the various parts of the CPU required to perform the instruction - e.g. gating data from the data bus into the Accumulator, triggering the adder circuitry in the ALU etc. Some authorities refer to these actions as 'Microinstructions' and the bit patterns stored in the ROM locations as 'Microcode'.

    http://www.cp.eng.chula.ac.th/~piak/teaching/dsys/micropgm.htm
    
    Extractions: mpgen translates "mspec.txt" into bits in "mpgm.txt". Each line of microword contains "bits" or "control signals" and "next address". This style is called "one address microprogram". There are other formats such as "two-address microprogram" and "multi-format microprogram". One-address microprogram is the simplest one. Each bit in control signals denotes an event or control in the data path, such as a select signal of a multiplexer or a load signal for a register. The number of control signals depends on the design of data path. In our abstraction, an event in data path is at register transfer level, source register to destination register, the data can passed through a combination function, denoted , where s, d are register and f is a combination function. The next address bits are the address for the event "goto label", the flow of control in the microprogram. It can be unconditional, conditional or multi-way branch depends on the simulator of control unit. The "width" of next address is ceiling(log_2 number of microword). The "width" of a microword is the number of control signals pluses the width of next address. There are two sections in "mspec.txt": signal definition and microprogram. The signal definition declares the name of control signals. The ordering of the signal denotes its bit position, from 0...n. This section starts with ".s". The microprogram section starts with ".m" and ends with ".e". Each microprogram line contains:

    Extractions: example Include the add-displacement to the ISA of S1 and modify S1 microprogram, the simulator is called "S1mx" Instruction addd r1, disp(r2) The displacement addressing is used to access a local variable in the stack frame (the activation record). r2 is used to hold the frame pointer. "disp" is the offset, which is the number of local variable, from the stack pointer. Let ir:disp be the bit 2..0 of the S-format (3 bit displacement) Meaning 1 (when the frame pointer itself must be dereferenced) R[ir:r1] = R[ir:r1] + M[ ir:disp + M[ R[ir:r2] ] ] Meaning 2 (when the frame pointer is in r2) R[ir:r1] = R[ir:r1] + M[ ir:disp + R[ir:r2] ] We will assume the second meaning (as it is faster) T = ADD( ir:disp, R[ir:r2]) R[ir:r1] = T To implement this instruction, the datapath must be modified to enable ALU to get an operand from the databus (to get ir:disp). We insert a multiplexor at one input of the ALU. Originally, the ALU has two input operands called RA, RB. Now the RB is "muxed" with the databus. The RA can be R[ir:r1] or R[ir:r2]. Note: this is not very clean, that RA can be either R[ir:r1] or R[ir:r2]. However it will suffice to illustrate the concept.

    Extractions: Goals: This laboratory exercise provides experience with microprogramming, following Tanenbaum's Mic-1 microprocessor (section 4.1). The lab asks you to interpret some microprograms and then write write your own simple microprograms. Resources: Throughout this lab, you will need to consult Figures 4-1, 4-2, 4-5, 4-6, and 4-7 (section 4.2) in Tanenbaum's text. Collaboration: As with the work for the previous labs, the following steps are to be done on paper collaboratively. Everyone should work in a group of two (preferred) or three students; within a group, each person should take responsibility for leading discussion for some of the problems. Steps for this Lab: In the following, assume the Local Variable register LV contains the base address of the integer array X. Consider Microprogram 1 which implements the C or Java statement X[2] = X[1] - X[0] This code may be printed with the command: dvips ~walker/public_html/courses/211.fa01/labs/micro-code-1.dvi Write a sentence or two to explain why each statement does what is claimed by the comment field (or correct any mistakes in the code, explaining what was wrong and how the correction fixes the problem). Why do you think the address of X[1] was stored both in the MAR and OPC?

    Extractions: Microprocessor architecture If we had to integrate all MicElem's components on a sigle chip, we could be tempted to save some gates at the cost of a higher microinstruction width (e.g. more control lines). For example, MicElem's arithmetic and logic unit , inputs 4 control lines US which are internally decoded to 1-of-16 for selecting the operation. Rather than keeping this method using 4 control lines the ALU has to decode, an alternative would be to have the microinstruction directly issuing 16 control lines, one of them selecting the current ALU operation. Such an alternative may appear during the design of several other control lines. Depending on the decisions taken, the result could be : very wide non-encoded horizontal microinstructions

It gives some extra details on the microinstruction fields, as well as exactly how memory accesses work. Please send any comments/questions to the tutor ( cs251@student.cs.uwaterloo.ca This is essentially the name of the line of microcode. You can choose anything you'd like. The label is useful for branching and jumping. For example, if you had a line called , you would use that name anytime you wanted to branch or jump to that line. This specifies the operation the ALU should do. The choices are add subtract , and func . The func operation is something you would rarely use. It is primarily there for the implementation of R-format instructions, where the ALU would use the function bits within that instruction to determine which operation to use. These refer to the sources of the two multiplexors that choose the inputs to the ALU. The ALU computation will use and as its operands. Please refer to the microprogrammed datapath as you read the following explanations.

    Extractions: The CPU and Microprogramming In this lecture we introduce a new logic element, the tristate gate , and describe how an op-code in the instruction register of a CPU is converted from a binary bit pattern into the sequence of operations required to execute the instruction that it represents. You can also download this lecture in Word DOC format or in Adobe PDF format. Buses and Tristate Gates A bus is a set of wires that connects two or more functional units in a computer together. A bus may be a simple affair that connects the data paths from two register together or it may be as complex as the PCI bus found in the PC that connects functional modules together and provides a wide range of facilities. Here we consider only very simple buses. A tristate gate is a logic device with a special output that can take a third state; that is, the new state is neither a nor a 1. Any logic gate can have a tristate output. Here we are interested only in the tristate buffer Figure 1 gives the symbol for two tristate buffer gates. Figure 1(a) is a tristate gate with an active-low control input E. When E is asserted high, the output of the gate Y is equal to its input X. When E is inactive low, the gate’s output Y is internally disconnected and the gate does not drive the output; that is, you cannot say what the output Y is because it is disconnected from the gate. Output Y will usually be connected to a bus and the signal level at Y when the gate is disabled will be that of the bus. Consequently, this output state is called
