Embedded systems based on FPGA (Field-Programmable Gate Arrays) must exhibit more performance for new applications. However, no high-performance superscalar soft processor is available on the FPGA, because the superscalar architecture is not suitable for FPGAs. High-performance superscalar processors execute instructions out-of-order and it is necessary to re-order instructions after execution. This...
Complex applications, such as multimedia, telephony or cryptography, in embedded systems must provide more and more performance that can be achieved by using multiple levels of parallelism. Today, FPGA are viable alternatives for these kinds of applications. Unfortunately, the available processors on FPGA do not provide sufficient performance. This work proposes the Morpheo tool that is a generator...
Deadlocks are an important issue in wormhole networks and a lot of works have been done on deadlock avoidance. Sufficient and necessary deadlock-freeness conditions have been proposed and used to build deadlock-free wormhole networks. But none of these works provide an efficient way to verify if a given network is deadlock-free. The present article proposes a new sufficient and necessary condition...
