Controller synthesis for digital signal processors
Viktor Öwall, Mats Torkelson · 1991
A tool for synthesis of control units in application-specific digital signal processors is presented. Synthesis of a control unit is based on micro instructions generated for each processor module and includes no use of predefined functional blocks. Complexity and partitioning of the controller are dependent on the structure of the micro program. The control unit synthesizer has been developed for synthesis of controllers to arbitrary digital signal processor architectures. The applications are targeted at digital radio communication algorithms. A hierarchical controller architecture suitable for frame-based and multi-sample-rate algorithms is synthesized by the tool. Processors for speech scrambling and digital adjustment of quadrature modulators have been designed and fabricated.>
