A method and system for providing remote procedure calls in a multiprocessing
system
is disclosed. The multiprocessing system includes a general purpose processor and
a plurality of network processors. Each of the plurality of network processors
includes a memory. The method and system comprises accessing a reserved address
in at least one of the network processors and initiating a software action by a
first portion of the reserved address. The method and system further includes pointing
to an address within the memory of the at least one network processor to be processed
based upon data in a second portion of the reserved address, wherein the data at
the address is processed. A system and method in accordance with the present invention
provides an indirect software jump in a microprocessing system through providing
a reserved address in memory of each of the reserved address includes two portions.
A first portion of the address triggers the software event requested by the general
purpose processor (for example) and a second portion of the reserved address is
utilized to process the data that was loaded at that address in the processor.
The indirect software jump allows a general purpose processor to execute software
on a network processor indirectly for custom application services or debug operations.
