The increasing device count and design complexity are posing significant challenges to post-silicon validation. Bug diagnosis is the most difficult step during post-silicon validation. Limited reproducibility and low testing speeds are common limitations in current testing techniques. Moreover, low observability defies full-speed testing approaches. Modern solutions like on-chip trace buffers alleviate...
This paper presents a multiprocessor architecture prototype on a field programmable gate arrays (FPGA) with support for hardware and software multithreading. Thanks to partial dynamic reconfiguration, this system can, at run time, spawn both software and hardware threads, sharing not only the general purpose soft-cores present in the architecture but also area on the FPGA. While on a standard single...
This paper presents a multiprocessor system on FPGA that adopts Direct Memory Access (DMA) mechanisms to move data between the external memory and the local memory of each processor. The system integrates all standard DMA primitives via a fast Application Programming Interface (API) and relies on interrupts having also the possibility to manage a command list. This interface allows to program the...
