Abstract
A data processing device is provided which has multiprocessors that can be configured on a cycle by cycle basis as loosely coupled or tightly coupled. Bit-stream Processing Unit (BPU),executes instructions from ROM,and accesses data from RAM,. Similarly, Arithmetic Unit (AU),executes instructions from ROM,and accesses data from RAM,. Both processor operate in parallel and exchange data by accessing RAM,. AU,can receive an instruction directive from BPU,directing it to perform a selected sequence of instructions in a loosely coupled manner. AU,can also receive an instruction directive from BPU,directing that a portion of AU,operationally replace a portion of BPU,for the duration of one instruction which allows data to be passed directly between the processors in a tightly coupled manner.
