MC6809是6800系列中高档处理机。它是一种比MC6800系列中其它处理机更快和更有效的高性能机器。即属于目前的6800系列的一部分,又保留了其它型号的软件和硬件兼容性。为满足用户需要MC6809发展了特殊用途的软件。因为它提供了更有效的新寻址码和一个辅助的扩充寄存器的装置,使MC6809更具有辅助现代软件技术的能力。如:模块式程序设计、浮动地址代码,递归程序设计、再入性和高级语言的生成。
MC6809 is the 6800 series of high-end processors. It is a faster and more efficient high-performance machine than the other processors in the MC6800 series. That is part of the current 6800 series, but also retains the other types of software and hardware compatibility. To meet the needs of users MC6809 developed a special purpose software. The MC6809 is more capable of assisting modern software technology because it provides a more efficient new addressing code and an auxiliary expansion register. Such as: modular programming, floating-address code, recursive programming, re-entry and high-level language generation.
