Mikrocodesimulator MikroSim 2010

... the ultimate CPU-Simulation Program

A Software Product of


Product Description

The Mikrocodesimulator is a Windows compatible application, on which microprocessor functionality can be simulated didactially. The user is able to investigate on various levels of abstraction how microcodes are understood as coded switch settings, how these codes are controlled executed in tacts, how microcodes are grouped in sequence to a microcode program placed in a ROM, and finally how a structured microcode program can interpret machine codes programmed in an external RAM for execution. In this manner, the operation range of single opating devices like ALU and memory composed to a programmable and versitile computer is perceptible and realizable. Whereas ALU, memory operation and the interaction are predefined, interaction control can be set as microcode commands in the ROM. By this, the user can design and implement his own designed machine codes into the ROM as OpCodes and is able to verify them step by step in single phases, tacts, and cycles. The utilisation of the application is remarkable intuitive. On the screen, the user enables the virtual devices belonging to the level of simulation. The content of the device interfaces can be modified by various editors easily in different numerative systems.

In the newest revision of the mikrcodesimulator, MikroSim 2010, the CPU application is strongly extended and improved. So, the simulator is the first application which is didactically leading to the nature of floating point caculation with single precision according to IEEE 754. Beyond this, the virtual CPU is connected with virtual peripherial hardware devices for input and output control via DMA bus, Inter-IC bus, and Interrupt control, which gives the virtual application a more application relevant relation to real application board hardware. By means of an integrated benchmark tool the user can determine the performance capability of the simulation tool and the effectivity of executed microcodes. Performance indices of the useres computer hardware measured in MIPS and FLOPS can be set in direct relation to the simulation speed measured in clock, micorocode, or OpCode excetution rate and to ALU calculation power for integer and floating point calculation.

History of Origin: 20 Years Microcode Simulation with MikroSim

Since almost 20 years, the Mikrocodesimulator is integral part of the lecture of the Philipps-University Marburg. The successful application of this tool is based on following aspects:

  • The program author himself is fascinated since schooldays by the automization of calculation processes on hardware. Based on own interest, a large commitment in programming useful applications, and being inspired by the precessor application got to know when visiting Informatik3-Lecture in WS92/93 given by Prof. Dr. Heinz-Peter Gumm,  the Mikrocodesimulator emerged the first time as powerful and intuitively usable Windows application.
  • The didactical concept has been applied, modificated and approved in WS1993/94 in several lectures at Philipps-Universität Marburg. The tool has demonstrated during this time being successful usable in lectures and for exercises.
  • The application has been awarded already at this time with the EUROPEAN ACADEMIC SOFTWARE AWARD 1994 in the category Computer Science.
  • Due to this success the program has been presented at the CeBit'95.
  • Since the first edition of the text book "Einführung in die Informatik"(Introduction into computer science) of Profs Heinz-Peter Gumm and Manfred Sommer (1st Ed.: Addision-Wesley, ISBN 3-89319-945-4) MikroSim is being discussed, and it is still part of the leatest edition (8th).

Comparison to Competitive Solutions

  • Currently, there is no other comparable and available CPU simulator for didactical use covering the scope of teaching.
  • Known simulators are programmed on DOS-basis at earlier days and are adapted to windows usage.
  • This tool is treating a virtual central processing unit next to application relevant devices. It is not specialized on a special kind of hardware and therefore easily usable for general introduction before starting special projects.
  • Mikrocodesimulator MikroSim 2000 is Windows95/98/Me/NT/2000 compatible and will be supported most probably by any compatible operation system in the future. MikroSim 2010 is optimized for Windows XP.
  • The application and its editors supporting during the microcoding process. No modification of complex source code, no usage of compilers and no special knowledge in programming languages is necessary.
  • Can be used in the educational courses as well as in exercises for private use.
  • Has been developed at the "Philipps-University Fachgebiet Informatik" and provides valuable contribution than more than 10 years in lectures of technical computer science. Several educational institutes have discovered its usefulness and using it already, too.
  • The program has been presented already several years ago on exhibition fairs and contests and judged as innovative and didactically extremly useful.

Conclusion: In its appearence, the Mikrocodesimulator MikroSim is unique. At this point it should be valuable to mention, that there are existing several software solutions, distributed as shareware or freeware, that are emerged from private interest or group work. Also useful hardware tools are available e.g. as microcontroller application boards and training platforms. But no solution is covering the scope of simulation such general, universal, and in a wide manner like MikroSim does.

Hardware and Operation Requirements


Licence Models

The simulator is availble as single-user licence or multi-user licence version.

  • Single-User Licence:
    The single user licence is user and hardware related. After registration, the application is only unlimited usable on the dedicated system, on which the simulator has been installed, tested and the registration file (i.e. Product Licence File, PLF) is created from. The PLF contains user and hardware relevant parameter filed for the registration. This licence can only be used on that single hardware, a valid internet connection is not neccessary to operate the software.
  • Multi-User Licence:
    A multi user licence is given to an institution, which is distributing the licences to its users for educational use. In contrast to the single user licence, the multi-user licence is not hardware or user related and needs no further registration. So, a usage of the program is possible without complicated licencing procedures. The benefit is that pupils and students can work on their own hardware if desired and are not limited to the IT equipment of the institution. Acquisition of this kind of licence is possible when ordering more than 10 licences.
  • Distributable Single-User Licence:
    This licence type allows the usage of MikroSim as registrated version as long the USB stick is connected to the computer in use. The licence is related to the USB stick and personilized to the institution that distributes the hardware related licence to their pupils and students. They can work on their own hardware if desired and they are not limited to the IT equipment of the institution. The usage of the program is possible without complicated licencing procedures. The additional costs for the USB hardware and the efforts of distributing and collecting the hardware licence is compensated by the program tool usage without Internet connection necessary.
