Latest Patents
Coutant's latest patents include a method and apparatus for the inter-operation of differing architectural and runtime conventions. This inventive mechanism allows an application to switch modes during its operation, between a compatibility or legacy mode for a previous architecture and a native mode for a current architecture. The mechanism includes an official function descriptor that describes information for accessing a function residing in one module. The official function descriptor has a legacy portion usable by a legacy module and a native portion usable by a native module. Additionally, the mechanism includes a linkage table that resides in a second module, referencing the function in the first module. Each portion of the official function descriptor corresponds to an entry that indicates the address location of the function and another entry that is a value for a register referring to the data segment corresponding to the load module containing the function. The information in the official function descriptor depends on whether the function is a legacy function or a native function.
Another significant patent is the cover instruction and asynchronous backing store switch. This computer-implemented method of switching contexts in a processor includes a register stack that has first and second portions. The processor includes a register stack engine to exchange information, in one of instruction execution dependent and independent modes, between the second portion and the storage area. The method involves determining whether an interrupt occurred and validating registers accordingly. The COVER instruction enables lightweight interrupt handling in a processor with a register stack.
