Microprogramming Lab CS63: Principles of Computer Organization Fall Semester, 1997 Ray Ontko Department of Computer Science Earlham College The purpose of this lab is to give you a chance to explore microprogramming and how the microprogram interacts with the hardware to implement a conventional machine language interpreter. Such simulators are used in the development of real microcode, and this lab is designed to give you a feel for what it is like to write (and debug) true machine language. Using the Mic-1 control store which I have entered (but not thoroughly tested), do each of the following and demonstrate it for your neighbor: Enter an instruction at address 2000(hex) in conventional memory. Use the Mac-1 instruction set (Fig. 4-14 on page 185) and pick an instruction that interests you. Clear the registers and step through the microcode by clock sub-cycle and watch carefully to see what's happening both in the hardware animation window, and in the microcode window. Does the instruction do exactly what you expected? Is it correct? Pick 8 sequential lines from the microprogram. Examine them carefully to see if they are identical (in description) to the corresponding lines in the text (Fig. 4-16, page 190-191). Now, check to see if each of them exacly implements the correct hardware functions. Note that Oddone has eliminated the TIR register (I have used A), and I have assumed that the X12 and Low8 registers have been pre-loaded with the AMASK and SMASK constants (0FFF and 00FF, respectively).

The system is based on the axiomatic architecture description language AADL, which is sufficiently rich to allow the specification of target architectures while providing a concise model for clocked microarchitectures. For each description A epsilon AADL of a host, it is shown how to construct systematically a (Hoare-style) axiomatic definition of an A-dependent high-level microprogramming language based on S*. The axiomatization of A's microoperations together with a powerful proof-rule dealing with the inherent low-level parallelism of horizontal architectures allow a complete axiomatic treatment of the timing behavior and dynamic conflicts of microprograms written in S*(A).

A Brief History of Microprogramming Mark Smotherman. Last updated March 1999 Definitions Although loose usage has sometimes equated the term "microprogramming" with the idea of "programming a microcomputer", this is not the standard definition. Rather, microprogramming is a systematic technique for implementing the control unit of a computer. It is a form of stored-program logic that substitutes for sequential-logic control circuitry. A processing unit in a computer system is composed of a data path and a control unit . The data path includes registers, function units such as ALUs (arithmetic and logic units) and shifters, interface units for main memory and/or I/O busses, and internal processor busses. The control unit governs the series of steps taken by the data path during the execution of a user-visible instruction, or macroinstruction (e.g., load, add, store, conditional branch). Each step in the execution of a macroinstruction is a transfer of information within the data path, possibly including the transformation of data, address, or instruction bits by the function units. A step is thus called a register transfer and is accomplished by gating out register contents (i.e., sending a copy) onto internal processor busses, selecting the operation of ALUs, shifters, etc., and gating in (i.e., receiving) new values for one or more registers.

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.

This paper describes a successful project using computer animation to teach the concepts of microprogramming to lower division computer science majors. The students write a simulator for the Mic-1 horizontal microcontroller described in the book Structured Computer Organization by Andrew Tanenbaum. The simulation is enhanced by the use of a graphical representation of the machine which animates the simulation. This creative use of computer animation enables the students to see the results of their simulation without having to write an extensive user interface. They can concentrate on implementing the instruction cycle which directly enhances their understanding of the Mic-1. The XTANGO animation package is used, making this portable to any Unix system with an X display. The user interface is available via anonymous ftp.

16. Microprogramming microprogramming Simplified microprogramming takes the principle onestep further by replacing the ROM with a ReadWrite store. http://classicbristolbuses.thornet.co.uk/NF/microprogram.html

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'.

[Top] [Next] [Prev] 12.5 Microprogramming We have concentrated so far on alternative methods for organizing the next-state logic. Now we can discuss various ways to organize the output signals controlling the data-path. We usually think of control signals as implemented by discrete logic, even if the implementation makes use of PALs or PLAs. Microprogramming , on the other hand, is an approach for implementing processor control in which the output signals are stored within a ROM. The two main variations of microprogramming are the horizontal and vertical methods. In the previous section, we already saw some distinction between horizontal and vertical next-state organizations. In horizontal microprogramming , there is one ROM output for each control point in the data-path. Vertical microprogramming is based on the observation that only a subset of these signals is ever asserted in a given state. Thus, the control outputs can be stored in the ROM in an encoded form, effectively reducing the width of the ROM word at the expense of some external decoding logic. Encoding the control signals may limit the data-path operations that can take place in parallel. If this is the case, we may need multiple ROM words to encode the same data-path operations that could be performed in a single horizontal ROM word.

[Top] [Next] [Prev] Exercises Moore Machine Figure 12.1 gives a Moore state diagram for implementing the simple CPU. Figure 12.2 showed the waveforms for the memory interface, to demonstrate the correct execution of a memory read operation in the instruction fetch states. Repeat this analysis for the state sequence OD, ST0, ST1, IF0 to verify that the interface signals correctly handle a memory write operation. Draw a timing diagram similar to Figure 12.2 labeled by the current state and including the waveforms for the memory address bus, memory databus, request, and read/write signals. Annotate the waveform with comments about the arrival of the appropriate data in the MAR and MBR registers. Synchronous Mealy Machine Section 12.1.2 described a strategy for constructing a synchronous Mealy machine by placing flip-flops between the inputs and the next-state logic. Assume that the state diagram of Figure 11.23 has been implemented as a synchronous Mealy machine in which the memory Wait signal is delayed by a synchronizing flip-flop. Verify that the memory interface operates correctly by drawing timing diagrams for all control signals asserted by the instruction fetch states. Include in your diagram the Wait signal as it leaves the memory subsystem and Wait as it is delayed by the synchronizing flip-flop.
