    摘要： According to the present invention, an anticipating cache memory loader is provided to "pre-load" the cache with the data and instructions most likely to be needed by the CPU once the currently executing task is completed or interrupted. The data and instructions most likely to be needed after the currently executing task is completed or executed is the same data and instructions that were loaded into the cache at the time the next scheduled task was last preempted or interrupted. By creating and storing an index to the contents of the cache for various tasks at the point in time the tasks are interrupted, the data and instructions previously swapped out of the cache can be retrieved from main memory and restored to the cache when needed. By using available bandwidth to pre-load the cache for the next scheduled task, the CPU can begin processing the next scheduled task more quickly and efficiently than if the present invention were not utilized. Using the present invention, CPU stalls will be reduced because the CPU will operate more efficiently without waiting for excessive periods of time for the cache to be loaded with relevant data and instructions.

    摘要： An apparatus and method for pre-loading a cache memory based on information contained in a compiler generated program map are disclosed. The program map is generated by the compiler at the time source code is compiled into object code. For each application program, the user would have this program map stored with the object file. At the beginning of the program execution cycle, the operating system will determine whether or not a program map exists for the application. If a program map exists, the operating system will load the program map into an area of RAM designated as the program map random access memory (RAM). The program map will be used to pre-load the cache with the appropriate data and instructions for the central processing unit (CPU) to process. The program mapping would be the address location of each jump/branch target that the CPU might encounter during the execution cycle. Each of these locations represent a starting point for a new code sequence. At the start of the map will be an identifier field to mark the start of the map. The next field in the program map will provide the entry point of the starting address of the application program. If a particular application program does not have a program map, the program and cache operation will remain unchanged. This feature provides backwards compatibility with existing application programs.

    摘要： An integrated circuit implements simple and efficient normal power to low power and low power to normal power transitions. Dedicated shadow latch circuits are added, each having a corresponding system latch. The state of the system latches is transferred to the shadow latches upon a transition from normal to low power mode and the stored information is transferred back to the system latches on the transition from low power to normal power operation. The shadow latches are optimized to minimize power usage during low power operation.
