Method and apparatus for handling interprocessor calls in a multiprocessor system

摘要

A multiprocessor arrangement in which the individual program functions of a program process are executed on different processors. Data shared by different program functions is stored in shared memory and the programs are stored in local memory of the individual processors. One processor calls for the execution of a program function by another processor by causing the program address and a pointer to the program function context to be loaded into a work queue of the called processor. Input/output modules are treated as processors. Facilities are provided for the transfer of blocks of data over the interconnection bus system. Virtual address are translated to physical addresses in one facility common to all processors.
