Special purpose micro-computer system, which can process graphic package independently, is designed and implemented in the printer.
This intelligent graphic printer subsystem, along with the host computer realizes an example of distributed processing with respect to off-loading much of the special processing from the host to an intelligent graphic device.
User oriented high-level plot module, UVERST is designed to facilitate users in programming.
Performance analysis is done to compare the characteristics of new system with that of old system.
Throughput is compared both in the host aspect and overall aspect.
단순한 graphic device인 printer 대신에 Graphics 전용의 특수한 micro-computer system을 printer 내부에 장치하여 host Computer 와는 별도로 parallel 하게 graphic process를 수행하는 Intelligent Graphic Printer Subsystem을 만들었다.
이것은 host computer로부터의 load를 줄이는 distributed processing을 graphic printer에 응용한 하나의 예가 된다.
User를 위한 high level의 plot module인 UVERST를 만들어 program시 user의 불편함을 덜고 graphics에의 응용범위를 넓혔다. 새로운 system과 기존의 system간의 performance를 throughput의 입장에서 host aspect와 overall aspect로 나누어 분석하였다.
