Method and arrangement for the power-efficient control of processors

摘要

A method is provided for the functional control of program and/or data flows in digital signal processors and processors, which have respective closed and separated modules for program and data flow control, working in parallel with computers. The method enables a power-efficient adaptation of the signal processing with the applied SIMD command-type in the individual paths and minimizes the emergence of the appearance of NOP-commands with which the VLIW-architecture of the processor must be supplied. The adaptation of the signal processing is achieved by individually controlling the parallel signal processing of the processor in the data paths (DP) which respectively belong to a first and second slice. For this purpose, a single slice halt outputted from an SSM register bank switches the register clockline according to state-dependent signal processing.
