They originated as peripheral processors for mainframe computers, taking on some routine tasks and freeing the processor for computation.
12.
The 6600 had support from ten supporting " peripheral processors " whose duties included reading the keyboard and driving the graphics displays.
13.
Each peripheral processor can communicate with any peripheral device if another peripheral processor is not using the data channel connected to that device.
14.
Each peripheral processor can communicate with any peripheral device if another peripheral processor is not using the data channel connected to that device.
15.
One of the peripheral processors ran a dedicated program called " DSD " ( Dynamic System Display ), which drove the console.
16.
These executed one instruction ( or a portion of an instruction ) from each of 10 different virtual processors ( called peripheral processors ) before returning to the first processor.
17.
No special job validation was required to assemble peripheral processor programs, but to be executed, such programs were required to installed into the operating system via special system editing commands.
18.
The peripheral processors in the true 180s were always 16-bit machines with the sign bit determining whether a 16 / 64 bit or 12 / 60 bit PP instruction was being executed.
19.
The CDC 6000 series computer is composed of four main functional devices : the central memory, one or two high-speed central processors, seven to ten peripheral processors ( Peripheral Processing Unit, or PPU ), and a display console.
20.
He did this by replacing I / O interrupts with a polled request issued by one of 10 so-called peripheral processors, which were built-in mini-computers that did all transfers in and out of the 6600's central memory.
