Improving Advanced Digital Signal Controller Applications Through Dual Core Solutions

The processing power for Digital Signal Controllers (DSCs) has been evolving to achieve the demanding requirements of today’s real-time control applications. In addition to requiring increased Digital Signal Processing (DSP) performance, embedded applications also require extra Central Processing Unit (CPU) performance to further enhance communications and implement new functional safety and management features. These factors are thus responsible for the way processing power is deployed in High-Integration Microcontrollers and Digital Signal Controllers.

Contemporary digital power supplies are an example of an application that demands stellar DSP performance coupled with high CPU performance to meet stringent system specifications. In this application, the DSC is responsible for precise and efficient control of energy conversion using mathematical algorithms and real-time PulseWidth Modulation (PWM) control. It also requires connectivity to relay real-time operational status and receive commands from a system-level management unit using protocols such as PMBus.

Another application example is an automotive fan or pump controller. While the closed-loop control of the motor leverages the signal processing capability of the DSC, communication with other modules in an automobile for control, status and diagnostics reporting is often accomplished through a protocol such as Controller Area Network Flexible Data (CAN-FD).
