Abstract
Messages are communicated between data processors (GPP, DSP) by appropriately configuring a software interrupt (SWI) on one of the data processors. The software interrupt is configurable for triggering in response to either of first and second predetermined conditions. When triggered, the software interrupt moves a message along a message path (toDSP, fromDSP) that supports communication between the data processors.
Claims37
A method of communicating between data processors, comprising:
- on one of the data processors, configuring a software interrupt that is configurable for triggering in response to either of first and second predetermined conditions;
- triggering the software interrupt in response to one of said predetermined conditions;
- and
- the software interrupt, when triggered, moving a message along a message path that supports communication between the data processors.
1 more element
A data processing apparatus, comprising:
- first and second data processors, one of said data processors operable for implementing a software interrupt that is configurable for triggering in response to either of first and second predetermined conditions;
- a message path coupled to said data processors for supporting communication therebetween;
- and
- said software interrupt operable when triggered for moving a message along said message path.
1 more element
A data processing apparatus, comprising:
- a message path for coupling to a further data processing apparatus to support communication with the further data processing apparatus;
- data processing circuitry coupled to said message path for implementing a software interrupt that is configurable for triggering in response to either of first and second predetermined conditions;
- and
- said software interrupt operable when triggered for moving a message along said message path.
