Abstract
A method for dynamically programming Field Programmable Gate Arrays (FPGA in a coprocessor, the coprocessor coupled to a processor, includes: beginning an execution of an application by the processor; receiving an instruction from the processor to the coprocessor to perform a function for the application; determining that the FPGA in the coprocessor is not programmed with logic for the function; fetching a configuration bit stream for the function; and programming the FPGA with the configuration bit stream. In this manner, the FPGA are programmable 'on the fly', i.e., dynamically during the execution of an application. The hardware acceleration and resource sharing advantages provided by the FPGA can be utilized more often by the application. Logic flexibility and space savings on the chip comprising thecoprocessor and processor are provided as well.
