Abstract

A dynamically adaptable communications processor includes a memory element, which includes executable content, and a control element, coupled with the memory element, that selectively implements the executable content to modify the dynamically adaptable communications processor to process data based, at least in part, on a type of communication channel from which the data is received.

Claims

1. An apparatus comprising:

a configuration memory to store configuration information for a plurality of different communication protocols selected from asynchronous transfer mode (ATM), packet-over-synchronous optical network (POS), and generic framing procedure (GFP);

control logic to determine a communication protocol associated with a data packet received over a communication channel, and retrieve configuration information corresponding to the determined communication protocol from the configuration memory; and

a dynamically configurable processing engine to process the data packets based on the configuration information; and

a context memory, wherein the control logic is further to store context data associated with a processed portion of the data packet after the processing of the data packet has stopped, and wherein the control logic is to retrieve the context data and process an unprocessed portion of the data packet using the configured processing engine.

2. The apparatus of claim 1, wherein the configuration information comprises cyclic redundancy check (CRC) algorithm configuration information.

3. The apparatus of claim 1, wherein the configuration information comprises scrambling algorithm configuration information.

4. The apparatus of claim 1, wherein the processing engine comprises an algorithm-based processing engine.

5. The apparatus of claim 1, further comprising an operation output memory to store outputs of operations performed by the processing engine on content of the data packet.

retrieving the context data; and

processing an unprocessed portion of the data packet using the configured communications processor.

7. The method of claim 6, wherein said retrieving the configuration information from the configuration memory comprises retrieving the configuration information from a configuration memory that stores configuration information for a plurality of disparate types of network architectures.

8. The method of claim 6, wherein said retrieving the configuration information train the configuration memory comprises retrieving the configuration information from a configuration memory that stores configuration information for at least asynchronous transfer mode (ATM), packet-over-synchronous optical network (POS), and generic framing procedure (GFP) protocols.
