Abstract
Apparatus and methods related to software architectures in a multiprocessor-based access device used in a content delivery and/or service provider network. In one embodiment, a software architecture is provided for a cable modem using a first type of digital processor (e.g., RISC core or similar), and a second type of digital processor (e.g., multi-core CPU). In one variant, the RISC processor is used as a cable modem stack processor, and the CPU processor is used as an application processor. A Linux (e.g., OpenWrt)-based software architecture is used wherein software components placed on both processors can communicate to effectuate, e.g., configuration changes to the device (including the cable modem stack). A mechanism to establish communications between the two different processor domains and retrieve the requested information based on existing (e.g., RPC) protocols is also disclosed.
