Cellular modem processing

A method of performing cellular modem processor operations comprising:

• performing a layer 1 processor operation in accordance with a cellular communication protocol by a cellular modem processor;
• performing a layer 2 processor operation in accordance with the cellular communication protocol by the cellular modem processor;
• and
• performing a layer 3 processor operation in accordance with the cellular communication protocol by the cellular modem processor
• accessing a first region of a shared memory by the cellular modem processor;
• accessing a second region of the shared memory by the cellular modem processor;
• accessing the second region of the shared memory by a second processor, wherein the first region is not accessible by the second processor.
