Patent ID: 8898716

Claim:
A digital communication system, the system comprising: an embedded Cable Modem (eCM) including a first System-On-Chip (SoC) comprising a Direct Memory Access (DMA) unit and a central processing unit, wherein the central process unit is configured to access a shared memory within the eCM SoC; and an embedded Set-Top Box (eSTB) coupled to the eCM by a packet transfer interface, the eSTB including a second SoC having a central processing unit coupled to the Direct Memory Access unit configured to access the shared memory within the eCM SoC as a local memory for the eSTB, wherein communication between the eCM and eSTB uses the shared memory, wherein communication between the eCM and the eSTB adds no header overhead and at least one buffer table configured to facilitate communication between the eCM and eSTB using the shared memory.
