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...
This paper proposes Flex Core, a hybrid processor architecture where an on-chip reconfigurable fabric (FPGA) is tightly coupled with the main processing core. Flex Core provides an efficient platform that can support a broad range of run-time monitoring and bookkeeping techniques. Unlike using custom hardware, which is more efficient but often extremely difficult and expensive to incorporate into...
In this paper, we present the design and implementation of an open-source reconfigurable very long instruction word (VLIW) multiprocessor system. This processor is implemented as a softcore on a field-programmable gate arrays (FPGA) and its instruction set architecture (ISA) is based on the Lx/ST200 ISA. This multiprocessor design is based on our earlier ??-VEX processor design. Since the ??-VEX processor...
In this paper we describe a mapping methodology for heterogeneous reconfigurable architectures consisting of one or more SW processors and one or more reconfigurable units, FPGAs. The mapping methodology consists of a separated track for a) the generation of the configurations for the FPGA by level-based and clustering-based temporal partitioning, and b) the scheduling of those configurations as well...
Multiprocessor platforms are gaining markets as a solution to boost general performance of processor beyond technological limitations that are present in single processors chips, Multi-processor in embedded systems also have a future in particular with applications like SDR(Software Defined Radio) where both high performance and high adaptability are required. Cryptographic algorithms implementation...
Soft-core based multiprocessor systems are getting very popular in the FPGA design world. There are many computer architectures that has been used for building multiprocessor systems on FPGAs, including SMP (symmetric multiprocessor). One of the main drawback of this SMP systems is the unavailability of operating systems that allow programming multi-threaded applications that make good use of the...
