The “RAM Units” used in this architecture implement a very specific type of communication that is implemented as a special channel representation in the programming model used to describe the applications running on this device. This makes the programming very specific to this device, and compilers for mapping the application expressed in a specific programming model to the architecture are available. 13 shows the Texas Instruments DaVinci architecture. The architecture is specific to video and audio applications, but, given the availability of two generic processing engines (ARM and TI DSP), the user still has some choice which execution engine to use for which task.
However, in order to ensure the feasibility of meeting performance, constraints must be checked and the power consumption optimized, which requires the exploration of various options of partitioning the parallel software. The MPSoC designer wants to ensure that selected applications can be run at the required performance and efficiency. This involves programming the computation-intensive parts of the applications and verification of MPSoC performance over a range of representative applications.
The rapidly increasing amount of data and its processing needs to be supported by storage on and off chip, leading to memory architecture and memory bandwidth as the third driver impacting multicore architectures. For instance, a detailed analysis of the Apple iPhone shows that, over the course of five generations from the original iPhone to the iPhone 4 S, the memory architecture and its access has changed fundamentally. As in most SoCs deployed in smartphone designs, the memory is implemented as a package-on-package (PoP) stack of DRAM on top of the SoC package.
