Abstract

Program monitor system 15 consists of a modular family of high-speed instrumentation devices attached to host computer system 10 having interface panel 11. The latter receives and translates information from computer 10, such as operation decoder signals, address control signals, etc., and can provide interrupt control signals, etc., to computer 10. Bus 18 connects panel 11 to a Bus-In-Control 12. Another bus 19, similar to bus 18, connects panel 11 in parallel to monitoring system 20, which can be similar to monitor 15.

Program Monitor

Program monitor system 15 consists of a modular family of high-speed instrumentation devices attached to host computer system 10 having interface panel 11. The latter receives and translates information from computer 10, such as operation decoder signals, address control signals, etc., and can provide interrupt control signals, etc., to computer 10. Bus 18 connects panel 11 to a Bus-In-Control 12. Another bus 19, similar to bus 18, connects panel 11 in parallel to monitoring system 20, which can be similar to monitor 15.

Control 12 provides the signals to a plurality of zones 1...n. A zone is a collection of closely related functional elements that perform a specific monitoring task. For example; one zone can count predetermined operation codes. Another zone can compare received functions against predetermined functions to identify the former. Another zone can detect and count the occurrence of program sequences or loops. Input/Output zone 31 controls tape and disk devices. Zone 36 controls graphic display 37 and hard copy recorder 38 which can display the monitored results.

ROS zone 21 and ROS control zone 22 control the monitoring setup of elements in each zone 1...n. Zone 21 contains, capacitor read-only storage cards CCROS which determine the available predetermined setup conditions for zones 1...n. Zone 22 selects and sequences the microwords stored in CCROS in zone 21. Signals are provided from zone 22 to control bus 23 to configure functional elements 13 within any zone. A number of elements 13 is provided within each zone, such as elements 13a, 13b, and 13c within zone 1. An element 13 is the basic unit addressable and configurable by zone 22 for a desired monitoring task.

Monitor 15 is capable of closely monitoring the operation of system 10 without interfering with such system's performance. Under certain circumstances, if required, monitor 15 can generate and transmit interrupts on bus 23 to system 10 in order to cause such system to perform in a required manner under special monitoring conditions. The measured results from the zones are provided to a...
