FIELD OF THE INVENTION
This invention generally relates to improved integrated circuits, computer systems, software products, and processes of operating integrated circuits and computers.
BACKGROUND OF THE INVENTION
Early computers required large amounts of space, occupying whole rooms. Since then minicomputers and desktop computers entered the marketplace.
Popular desktop computers have included the “Apple” (Motorola 680x0 microprocessor-based) and “IBM-compatible” (Intel or other x86 microprocessor-based) varieties, also known as personal computers (PCs) which have become very popular for office and home use. Also, high-end desk top computers called workstations based on a number of superscalar and other very-high-performance microprocessors such as the SuperSPARC microprocessor have been introduced.
In a further development, a notebook-size or palm-top computer is optionally battery powered for portable user applications. Such notebook and smaller computers challenge the art in demands for conflicting goals of miniaturization, ever higher speed, performance and flexibility, and long life between battery recharges. Also, a desktop enclosure called a docking station has the portable computer fit into the docking station, and improvements in such portable-computer/docking-station systems are desirable. However, all these systems are generally CPU-centric in the sense that the selection of the CPU determines the system's processing capabilities and add-in-cards are added to the CPU to add specific applications or functions, such as modem or multimedia.
Software for computers and the processes and concepts for developing and understanding both hardware and software have spawned an intricate terminology. For an introduction, see references hereby incorporated herein by reference, and listed below:

Improvements in circuits, integrated circuit devices, computer systems of all types, methods and processes of their operation, and software products, to address all the above-mentioned challenges, among others, are desirable, as described herein.
SUMMARY OF THE INVENTION
Generally, and in one form of the present invention, a process of operating a computer system is provided. The computer system has a storage holding an operating system and an application program, a first processor having an instruction set, and a second processor having a different instruction set. The process includes first step of 1) running at least some of the operating system on the first processor so that the first processor sets up for at least part of the application program at run time at least one second processor object. A second step concurrently runs the second processor to access the second processor object and thereby determine operations for the second processor to access second processor instructions for that part of the application program and data to be processed according to the second processor instructions, and runs the second processor to process the data according to the second processor instructions.
Other processes, systems, devices and methods are also claimed.
