  • System for automatically generating optimized codes
    Patent number: 7979852
    Abstract: The inventive system for automatically generating optimizes codes (19) which are operational on a predefined hardware platform (90) comprises at least one processor which is (91) based on code sources (17) provided by users and comprises means (51, 52) for receiving symbolic code sequences or standard sequences (1) representative for the processor (91) behavior in terms of performance for a predetermined application area, means (53), for receiving static parameters (2), means (55) for receiving dynamic parameters (7), an analysing device (10) for defining optimization rules (9) on the basis of performance tests and measures determined on the basis of the standard sequences (1) and the static (2) and dynamic (7) parameters, a device (80) for optimizing and generating the code receiving the standard sequences (1) and the optimization rules (9) for examining the code sources (17) of the users, detecting optimizable loops, decomposing into cores and for assembling and injecting the codes in such a way that the op

  • Data exchange between cooperating processors
    Publication number: 20070168646
    Abstract: One embodiment relates to a computer apparatus including at least a microprocessor having an address space, an accelerator configured to cooperatively execute a program with the microprocessor, and a data register in the accelerator. The data register in the accelerator is mapped into the memory address space of the microprocessor. Other embodiments are also disclosed.
