摘要： Provides methods, systems and apparatus for coupling a general purpose processor (GPP) to an application specific instruction set processor (ASIP) in such a manner that the GPP can include execute instructions that do not normally comprise part of its instruction set architecture (ISA). The GPP is coupled to the ASIP via a coprocessor port such that instructions issued by the GPP to the port are conveyed to a novel pre-decoder module of the ASIP. The pre-decoder module translates the GPP instruction into operation codes for ASIP instructions to be executed in the ASIP or to an address in the ASIP instruction memory that identifies a start address for a plurality of ASIP instructions defining a complex application specific function. Once the ASIP has executed the instructions it shares the result of the execution with the GPP. In this way, the GPP takes advantage of the ASIP in its ability to more quickly execute an application specific program/procedure.

摘要： Methods, systems and apparatus for timer management of an element processing system wherein timer intervals related to elements to be processed can be handled in a time-efficient manner. An example method is a method for detecting a timeout of elements in an element processing system wherein a timer value, indicating a timeout interval with respect to a given time base, is assigned to each of the elements when processed. From a number of elements processed, the timer value indicating a minimum timeout interval to expire is determined out of the number of timer values assigned to the number of elements being processed.

摘要： A method for dynamically programming Field Programmable Gate Arrays (FPGAs) 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 the coprocessor and processor are provided as well.
