Abstract:
A cable modem system that interfaces at least two processors to transfer data between the at least two processors, the cable modem system comprising:a first processor; a second processor; a memory that stores a specification within a first portion of the memory, the specification governs the transfer of the data between the first processor and the second processor, one of the first processor and the second processor writes the data to a second portion of the memory; a semaphore circuitry determines which of the first processor and the second processor writes the data to the second portion of the memory; an interrupt control circuitry that notifies the other of the first processor and the second processor to read the data from the second portion of the memory; and a bus that communicatively couples the first processor, the second processor, the semaphore circuitry, the interrupt control circuitry, and the memory.
