摘要： Embodiments of the invention include a mechanism for explicit communication in a clustered multiprocessor system that supports low-latency, protected, user-mode, communication across the machine boundaries of a clustered multiprocessor. Data transport may be accomplished over persistent, unidirectional, point-to point connections, each of which may be embodied in a small amount of state at each end, along with a statically allocated per-connection memory buffer, which may be directly accessible to the transport mechanism at both ends of each notional link. System Memory protection may be afforded by operating system (“OS”) facilitated allocation of both restricted control of the network interface, and responsibility for data transport, to an application thread that may execute in the context of the processor-managed virtual address space. Connection buffer protection may be afforded by restricting access to connection state to those entries associated with the currently controlling thread.

摘要： A system and method for compiling computer code written to conform to a high-level language standard to generate a unified executable containing the hardware logic for a reconfigurable processor, the instructions for a traditional processor (instruction processor), and the associated support code for managing execution on a hybrid hardware platform. Explicit knowledge of writing hardware-level design code is not required since the problem can be represented in a high-level language syntax. A top-level driver invokes a standard-conforming compiler that provides syntactic and semantic analysis. The driver invokes a compilation phase that translates the CFG representation being generated into a hybrid controlflow-dataflow graph representation representing optimized pipelined logic which may be processed into a hardware description representation. The driver invokes a hardware description language (HDL) compiler to produce a netlist file that can be used to start the place-and-route compilation needed to produce a bitstream for the reconfigurable computer. The programming environment then provides support for taking the output from the compilation driver and combining all the necessary components together to produce a unified executable capable of running on both the instruction processor and reconfigurable processor.
