Capacitance monitoring is one of the important issues for a modular multilevel converter (MMC) to obtain high reliability. Since pulsewidth modulation usually implemented in field-programmable gate array (FPGA), produced precise switching states FPGA cannot be directly accessed by top digital signal processor (DSP) controller, which poses challenges existing capacitance methods based on MMC. Th...

Embedded systems often use a heterogeneous multi-core processor to improve performance and energy efficiency. This multi-core processor is composed of a general purpose processor (GPP), which manages the program flow and I/O, and a digital signal processor (DSP), which processes mass data. An inter-processor communication (IPC) mechanism is thus required to exchange data between a GPP and a DSP...

This paper presents BURAQ, a DSP development framework, which aims at optimizing cost, efficiency and turn around time of System-On-Chip development. BURAQ accepts an Instruction and Architecture description (IAD) file that represents the DSP and its instruction set at a higher level of abstraction, in a proprietary language. The system then synthesizes a complete hardware description of the pr...

We propose novel multicore architecture in which dual processors (positive-true processor element and negativetrue processor element: pPE and nPE) can be combined and serve as a low-voltage/high-performance single PE. The coupling processor occupies a double area, but it operates at a lower voltage or faster than the original processor. The proposed scheme is suitable to voltage scaling on mult...
