Abstract
The programme controlled system for process applications uses a bit processor for operation of peripherals requiring a single bit order and a word processor for peripherals requiring a coded word of information. A digital word processor (WP) is coupled over an interface bus (DS) with standard peripherals (STP) such as page memories, displays, tape etc., process peripherals (PRP) such as multiplexers, D/A converters etc. and also any associated processor (VER). A programme memory (PSP) couples over the bus with a co-ordinate (KOR) tied to the bit processor (BP). The bit processor (BP) connects with an interface bus and communicates with single bit output peripherals (BA), bit memory (BSP) and bit input peripherals (BE). The programme memory (PSP) holds both the instructions for the word and bit memories alternately and enables the fast operation of the bit processor to be fully utilised.
