| dc.description.abstract | Both analog and digital computation have certain comparative advantages and disadvantages. A hybrid computer system provides an interface between analog and digital computing elements. With the use of a hybrid computer, the programmer can utilize the best features of both analog and digital computation. A hybrid interface was constructed to couple the GE-4020 digital computer and the EAI-580 analog computer. The interface provides a method for controlling and sensing the analog computer operating mode from the digital computer. It also enables the digital computer to control the coefficient settings of servo-controlled potentiometers. The overload status of the analog amplifiers can be detected from the digital computer. The outputs and derivatives of amplifiers can be converted from analog to digital and brought into the digital program. A logic signal communication path is provided between a digital logic patch panel and the digital computer. In addition, a number of supplemental data paths are provided to expand the flexibility of the hybrid system. An analog output section is available which can provide a set of analog output values to analog patch trunks under digital computer control. An analog input section is available which can sample a set of analog patch trunk signals and convert them to digital for use by the digital program. A set of high-speed digitally-controlled electronic attenuators is provided. A number of interrupts are available to allow the analog program to interrupt the digital program. Thus, the hybrid interface provides a complete two-way control and data path between the analog and digital computers, Documentation is provided at both the language level and the machine hardware level. Emphasis is placed on a description of the user-system interface. The digital control commands and analog system characteristics are described in detail. Information is provided which will aid in further hardware development. | en |
