Estimating the term…
A method to manage the operation of a coprocessor in a virtual memory type data processing system in which an Input/Output channel and an Input/output channel controller interconnect the coprocessor to the main processor and system memory. A Virtual Resource Manager (VRM) comprising a group of interrelated software programs function in the system to establish virtual machines that execute application programs concurrently. A Coprocessor Manager component of the VRM establishes a Virtual Machine in which the compressor executes application programs that cannot be executed on the main processor. The coprocessor is mounted on an integrated circuit card which is inserted into a `mother board` socket which contains the main processor and related components.
A method for use in a virtual machine type data processing system which comprises a main processor, a coprocessor, a first device independent operating system which executes directly only on said main processor and a second device dependent operating system which executes directly only on said coprocessor, and a Virtual Resource Manager consisting of a plurality of interrelated programming components which are executable on said main processor for selectively establishing at least two different type virtual machines which operate to process first and second application programs, each of which runs under a different one of said operating systems, said method comprising the following steps;
