Multi-core system is becoming the next generation embedded design platform. Heterogeneous and homogeneous processor cores integrated in Multiple Instruction Multiple Data (MIMD) System-on-a-Chip (SoC) to provide complex services, e.g. smart phones, is coming up in the horizon. However, distributed programming is a difficult problem in such systems. Today, only in very few MIMD SoC designs we can find...
Considering the ability to perform multi-processor architecture systems on FPGA, partial reconfiguration is an opportunity to improve weak soft-core performances by specializing coprocessors according to context-dependent application needs. But at the application level, there is a need for straightforward programming models that allow applications to be easily mapped on an ad hoc architecture without...
One trend dealing with the growing computational power needs is to implement multi-processor system-on-a-chip (MPSoC) using Commercial Off-The-Shelf (COTS) partially reconfigurable architectures. However the low Non-Recurring Engineering (NRE) cost solution provided by commercial FPGAs must take into account the high sensitivity to electronic defects. Fault-tolerance schemes, which prevent their architectures...
Modern Systems-on-Chip (SoC) development is moving toward multiprocessor-based design. Embedded systems have evolved from an uniprocessor to a multiprocessor approach, seeking better performance and less energy consumption. It is widely accepted that Multiprocessor Systems-on-Chip (MPSoC) will become the predominant class of embedded systems in future. In addition, advances in FPGA technology makes...
FPGA based multiprocessor SoC (MPSoC) is an on-chip multiprocessor with fully programmable feature which can reduce development cost and achieve performance requirement. In order to provide an MPSoC with the low-overhead communication and synchronization methods, this paper attempts to introduce the TSVM (tagged shared variable memory) cache to a snooping cache on the MPSoC. The TSVM cache can improve...
