Abstract

A digital data processor comprises a high-speed processor (50) having input ports (52) and output ports (54), a memory (56), and a slow-speed support processor (58), the memory being accessible to both the high-speed and slow-speed processors. Data exchange between the high-speed processor and the memory does not interrupt the high-speed processor. The high-speed processor can effect processing in dependence upon parameters written into the memory by the slow-speed processor and which may have been derived by analysing data supplied to the slow- speed processor from the high-speed processor via the memory. <IMAGE>
