Method, apparatus, and computer program product for inter-core communication in multi-core processors

A method, comprising:

• storing with a shared inter-core communication unit in a multi-core processor, first data produced by a producer processor core, in a first token memory located at a first memory address of a memory address space;
• connecting with the shared inter-core communication unit, the first token memory to a consumer processor core of the multi-core processor, to load the first data from the first token memory into the consumer processor core, in response to a first-type command from the producer processor core;
• connecting with the shared inter-core communication unit, an input token memory located at an input token memory address of the memory address space, to the producer processor core of the multi-core processor, to load input data from the first token memory into the producer processor core, in response to a second-type command from the producer processor core;
• storing with the shared inter-core communication unit, result data produced by the producer processor core from the input data, the result data being the first data stored in the first token memory;
• and
• connecting with the shared inter-core communication unit, the first token memory to the consumer processor core of the multi-core processor, to load the result data from the first token memory into the consumer processor core, in response to the first-type command from the producer processor core.

A computer program product comprising computer executable program code recorded on a computer readable non-transitory storage medium, the computer executable program code, when executed by a computer processor, cause an apparatus to at least perform the following:

• storing with a shared inter-core communication unit in a multi-core processor, first data produced by a producer processor core, in a first token memory located at a first memory address of a memory address space;
• connecting with the shared inter-core communication unit, the first token memory to a consumer processor core of the multi-core processor, to load the first data from the first token memory into the consumer processor core, in response to a first-type command from the producer processor core;
• connecting with the shared inter-core communication unit, an input token memory located at an input token memory address of the memory address space, to the producer processor core of the multi-core processor, to load input data from the first token memory into the producer processor core, in response to a second-type command from the producer processor core;
• storing with the shared inter-core communication unit, result data produced by the producer processor core from the input data, the result data being the first data stored in the first token memory;
• and
• connecting with the shared inter-core communication unit, the first token memory to the consumer processor core of the multi-core processor, to load the result data from the first token memory into the consumer processor core, in response to the first-type command from the producer processor core.
