    • Provides evaluation and management of system resources in a data processing system, particularly in a SoC device and for optimizing the operation of the system wherein the system having a plurality of components each operable to process dedicated tasks in the data processing system, wherein each of the components has its associated current resource usages depending on the currently processed task and/or its future resource usage depending on the tasks to be processed next, wherein the resource usage indicates the type of resources and the amount of resources used, wherein the processing of the task of at least one of the components can be modified to adapt the resource usage of this or other component. A method including: determining operating states; estimating current and future resource usage; if necessary adapting task processing according to a predefined scheme to reduce the-resource usage.

    • 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.
    • 提供用于将通用处理器(GPP)耦合到应用特定指令集处理器(ASIP)的方法,系统和装置,使得GPP可以包括通常不包括其指令集架构(ISA)的一部分的执行指令, 。 GPP通过协处理器端口耦合到ASIP,使得GPP向端口发出的指令被传送到ASIP的新型预解码器模块。 预解码器模块将GPP指令转换为在ASIP中执行的ASIP指令的操作码或ASIP指令存储器中的一个地址,该地址标识用于定义复杂的专用功能的多个ASIP指令的起始地址。 一旦ASIP执行了指令,它将与GPP共享执行结果。 以这种方式,GPP利用ASIP更快地执行特定应用程序/程序的能力。
