United States Patent 6,308,255 October 23, 2001
Symmetrical multiprocessing bus and chipset used for coprocessor support allowing non-native code to run in a system

Abstract

A computer system includes a host processor and an emulation coprocessor. The host processor includes hardware configured to execute instructions defined by a host instruction set architecture, while the emulation coprocessor includes hardware configured to execute instructions defined by a different instruction set architecture from the host instruction set architecture ("the foreign instruction set architecture"). According to one embodiment, the host processor executes operating system code as well as application programs which are coded in the host instruction set architecture. Upon initiation of a foreign application program, the host processor communicates with the emulation coprocessor to cause the emulation coprocessor to execute the foreign application program.

United States Patent 6,480,952
Emulation coprocessor

Abstract

A computer system employing a host processor and an emulation coprocessor. The host processor includes hardware configured to execute instructions defined by a host instruction set architecture, while the emulation coprocessor includes hardware configured to execute instructions defined by a different instruction set architecture from the host instruction set architecture ("the foreign instruction set architecture"). The host processor core executes operating system code as well as application programs which are coded in the host instruction set architecture. Upon initiation of a foreign application program, the host processor core communicates with the emulation coprocessor core to cause the emulation coprocessor core to execute the foreign application program. Accordingly, application programs coded according to the foreign instruction set architecture can be executed directly in hardware
