METHOD AND DEVICE USING FPGA TECHNOLOGY WITH MICROPROCESSOR FOR SPEED-UP OF RECONFIGURABLE INSTRUCTION LEVEL BY HARDWARE

摘要

PPROBLEM TO BE SOLVED: To provide a method and device for dynamically programming FPGA during execution of an application. PSOLUTION: The method for dynamically programming FPGA (field programmable gate array)210 in a co-processor connected to a processor comprises steps of starting execution of the application by the processor; receiving an instruction which requests execution of a function for the application from the processor by the co-processor; determining that the FPGA in the co-processor is not programmed with a function logic; fetching a configuration bit stream for function; and programming the FPGA with the configuration bit stream 220. Therefore, the FPGA can be dynamically programmed during execution of the application. The application can further frequently use advantages of acceleration and resource sharing by hardware provided by the FPGA. PCOPYRIGHT: (C)2006,JPO&NCIPI
