目前最新的语言信号处理机都用位片式快速微处理器加硬件乘法器构成,全部操作用软件实现。本文提出了由多个速度较低的微处理器如Intel公司的8080A、8085或Motorola公司的6800构成语言处理机的方案。并且在对硬件和软件进行实验的基础上,对多机系统的一些关键问题如提高运算速度的措施、微处理器之间的通信与有关接口技术、系统的管理、硬件软件的划分等,提出了具体的方法。这种体制对于目前在国内的数字通信领域中迅速推广使用微处理器是有价值的。从长远看,随着MOS型微处理器的发展,也将会有竞争能力。
At present, the latest language signal processors are all composed of bit slice type fast microprocessors and hardware multipliers, and all the operations are implemented by software. This paper presents a solution to a language processor consisting of a number of slower microprocessors, such as Intel’s 8080A, 8085 or Motorola’s 6800. Based on the experiment of hardware and software, some key problems of multi-machine system, such as the measures to improve the computing speed, the communication between microprocessors and the related interface technology, the management of the system and the division of hardware and software are put forward The specific method. Such a system is valuable for rapidly popularizing microprocessors in the domestic field of digital communications. In the long run, with the development of MOS microprocessor, it will also be competitive.
