Inter-core (also called Inter-CPU or Inter-Processor) communication on the C6474 multi-core DSP devices can be accomplished using the on-chip inter-processor communication (IPC) module. The main function of the IPC module is to provide inter-core interrupts. Optionally, flags can be sent along with an interrupt for implementation or more advanced inter-core communication protocols.The purpose o

Today's digital signal processor (DSP) architectures are confronted with the tough requirement of addressing a wide-range of standards and meeting a cost-effective performance/power trade-off. Increasing raw million instructions per second (MIPS) performance just by running at a higher frequency is not possible anymore since leakage is becoming a dominant factor with shrinking silicon geometries.

feb 11, 2011In most customer applications, a high level of decoding bit error rate (BER) performance is required. Since Convolutional codes and Turbo codes are widely used in wireless communication systems, TI DSPs integrate two high-performance embedded coprocessors (enhanced Viterbi decoder coprocessor and enhanced Turbo decoder coprocessor) that significantly speed up channel-decoding operations on-chip.

As application complexity continues to grow, we have reached a limit on increasing performance by merely scaling clock speed. To meet the ever-increasing processing demand, modern System-On-Chip solutions contain multiple processing cores. The dilemma is how to map applications to multicore devices. In this paper, we present a programming methodology for converting applications to run on multicore
