Abstract
In a shared-memory multiprocessor having plural processors that share a shared memory, each have an address space that is respectively independent in the shared memory and are configured to be capable of inter-processor communication using a bus, a first processor makes a procedure call to a second processor by specifying an address in the address space of the second processor. In response to the procedure call, by initiating and executing the procedure located at the address specified by the first processor, the second processor initiates the procedure at a high speed.
Claims9
A procedure calling method in a shared-memory multiprocessor having processors that are capable of inter-processor communication using a bus, share a memory and each have an address space that is respectively independent in the memory, the procedure calling method whereby a first processor of the shared-memory multiprocessor makes a procedure call to a second processor thereof and comprising:
- making the procedure call by the first processor specifying an address in the address space of the second processor;
- and
- initiating and executing, by the second processor, a procedure located at the address specified by the first processor.
A procedure calling method in a shared-memory multiprocessor having processors that are capable of inter-processor communication using a bus, share a memory and each have an address space that is respectively independent in the memory, the procedure calling method whereby a first processor of the shared-memory multiprocessor makes a procedure call to a second processor thereof and comprising:
- specifying, by the first processor, an address in the address space of the second processor;
