Embedded DSP Software Design Using Multicore System-on-a-Chip (SoC) Architectures

Multicore System-on-a-Chip

Designing and building embedded systems is a difficult task, given the inherent scarcity of resources in embedded systems (processing power, memory, throughput, battery life, and cost). Various trade-offs are made between these resources when designing an embedded system. Modern embedded systems are using devices with multiple processing units manufactured on a single chip, creating a sort of multicore system-on-a-chip (SoC) can increase the processing power and throughput of the system while at the same time increasing the battery life and reducing the overall cost. One example of a DSP based SoC is shown in Figure 11.1. Multicore ...
