    摘要: A method of operating a multiple processor device. A first word of a sequence of words is received in a register. A target processor is determined from the first word and the target processor is interrupted. An input ready bit is set and first word from in the register is read with the target processor. A number of words in the sequence to follow the first word determined from the first word. A word counter is set and the input ready bit is cleared with the target processor. The target processor is returned to main code execution.

    摘要: A method of exchanging messages between first and second processors. A pending flag in a first register is polled by the first processor and if the flag is in a first selected logic state, a message is written into a second register with the first processor. The pending flag is set to a second selected logic state with the first processor and an interrupt to the second processor is generated. The message is read from the second register with the second processor when the pending flag is in the second logic state. The pending flag set to the first logic state with the second processor.

    摘要: A method of operating shared memory in a multiple processor system. A token is by default maintained with a first processor, the token enabling access to shared memory. A determination is made that a second processor requires access to shared memory. A determination is also made as to whether the first processor is accessing to the shared memory. The token is transferred the second processor if the first processor is not accessing the shared memory. The second processor accesses the shared memory with the token.

    摘要: A method of processing a stream of audio information received by a multiple processor audio decoder. Processing operations are performed by a first processor on the stream of audio information to produce at set of results. The first processor writes the set of results into a shared memory and a flag is set indicating that the results are ready. In response to the flag, a second processor reads the results from shared memory. When the results have been read from shared memory, the second processor sends a command to the first processor. The first processor then clears the flag.
