These controllers have been quite a hit. Thousands have been sold, just as seen in the picture on the facing page. Did you know, these boards can be customized? Whether it is adding a feature to the NMIT-0020 (target version) to make it closer to the NMIX-0020 (development version), or, a complete redesign to meet a specific form -factor and function, even a different CPU, you should take advantage of the customization New Micros offers. From the biggest automotive giants, to the smallest one -man -shops, companies use New Micros to design, layout, program, and/or manufacture just the right controller, with just the right features. You should, too. Some customers asked for A/D and D/A features on the basic NMIT-0020 design.

  • Welcher Typ Ist Der Co...? Typ-Identifizierung Von CPU Und Coprozessor in MS-DOS-Pcs
    Welcher Typ ist der Co...? Typ-Identifizierung von CPU und Coprozessor in MS-DOS-PCs Das Ziel wohl jeden Softwareentwicklers ist es, die Anwender seines Programms rundum zufriedenzustellen. Eines der vielen Kriterien, das der Programmierer dabei beherzigen muß, ist die optimale Ausnutzung der CPU-(und Coprozessor-)Leistung im Anwender-PC, denn so etwas bringt Geschwindigkeit. Wegen der vielen unterschiedlichen Prozessortypen muß ein gutes Programm also vor dem Start selbst herausfinden, von welchem „Rechenchef“ es demnächst bearbeitet werden wird. Wie es das tut, das lesen Sie hier. Im Abstand von nur wenigen Jahren brachte Intel immer neue Generationen der 80x86-CPU-Reihe heraus, jede mit einem spürbaren Leistungs-Plus im Vergleich zu den Vorgängern. Dazu kam eine ständige Erhöhung der Taktfrequenzen von ursprünglich 5 MHz beim 8086 bis zu fast 50 MHz heutzutage. Auch die Befehlssätze wurden ständig erweitert, und beim Übergang vom 80286 zum 80386 wechselte man sogar von einer 16- auf eine 32-Bit-Architektur. Alle denkbaren Hardware- Konfigurationen, dazu die Coprozessoren, findet man heute bei den PC-Anwendern vor, weshalb der Softwareentwickler vor der schwierigen Frage steht: „Auf welche CPU und auf welchen Coprozessor soll ich mein Programm zurechtschneidern?“ Der Programmierer kann sich natürlich auf die vom 8086 gebotene Power beschränken. Eine solche Software verschenkt dann auf 386/486-Rechnern einen Großteil der potentiellen Leistung. Er kann andererseits die speziellen Möglichkeiten der modernen Hochleistungschips ausnutzen und nimmt dabei in Kauf, daß seine Software auf Millionen noch existierender 8086- oder 80286-Computer nicht lauffähig ist. Die beste Lösung ist aber doch letztlich, wenn ein Programm die Hardware-Ressourcen optimal nutzt.
