Abstract
A method of communicating between a first and a second processor includes the first processor sending a datum over a common control bus, and the second processor receiving the datum from the common control bus.
Claims38
A method of communicating between a first processor and a second processor comprising:
- sending a datum from the first processor over a common control bus;
- receiving the datum at the second processor from the common control bus;
- and
- sending a control signal from the first processor over the common control bus to alert the second processor that the first processor is about to send data prior to the sending of the datum.
1 more element
A system for communicating between processors comprising:
- a first processor and a second processor;
- a first bus for communicating between the first and second processors and peripheral devices;
- and
- a control bus for controlling communications on the first bus, the control bus being further configured for communicating data between the first processor and the second processor.
1 more element
A computer processor comprising:
- a first bus interface for communicating with peripherals;
- a control bus interface for controlling communications over the first bus interface;
- a controller for controlling communications over the first bus interface using the second bus interface, the controller being further configured to communicate with a second processor over the control bus interface.
An article comprising a computer-readable medium which stores computer-executable instructions for communicating data from a first processor to second processor, the instructions causing:
- the first processor to send a datum over a common control bus to the second processor;
- and
- the second processor to receive the datum from the common control bus, wherein the instructions are configured to communicate the datum over the common control bus for controlling communications between at least one of the processors and at least one peripheral device.
