一、SYM-1监控程序特点在一个功能较强的成熟的监控程序上扩充用户命令,以适应应用程序的需要,是提高系统设计的性能价格比的有效方法。美国SYNERTEK公司的SYM-1微型单板计算机,是以6502CPU为核心的一种功能较强的单板微型机。机上配有4KROM的超级监控程序(SUPERMON MONITOR)。它具有如下一些优点: 1.采用系统随机存贮器,存放各种转移矢量和常数,而且可用解除写保护随时改变这些量,使不同方式工作的设备控制程序都能在同一监控中实现。 2.采用多参数命令(共有0～3个参数)方式,增强了命令的功能。 3.能对RAM的2K、3K、4K分别进行写保护,
First, the SYM-1 monitoring program features In a more mature and mature monitoring procedures to expand user commands to meet the needs of the application is to improve the system design, an effective way to achieve cost-effective. US SYNERTEK SYM-1 micro-single-board computer, is 6502CPU core of a more powerful single-board microcomputer. Machine equipped with 4KROM Super Monitor (SUPERMON MONITOR). It has the following advantages: 1. The use of system RAM, storing a variety of transfer vectors and constants, and can be used to relieve write-protection at any time to change these quantities, so that different ways of working equipment control procedures can be achieved in the same monitoring. 2 multi-parameter command (a total of 0 to 3 parameters) mode, enhanced command functions. 3 can RAM 2K, 3K, 4K write protection, respectively,
