A cellular mobile station including a modem processor and memory. The memory includes instructions for the modem processor to perform layerprocessor operations, layerprocessor operations, and layerprocessor operations. The modem processor executes the instructions to perform processor operations for the cellular mobile station to communication data as per a cellular communications protocol. In one example, the mobile station includes different levels of memory to provide different deterministic access times.

A cellular mobile station including a modem processor and memory. The memory includes instructions for the modem processor to perform layer 1 processor operations, layer 2 processor operations, and layer 3 processor operations. The modem processor executes the instructions to perform processor operations for the cellular mobile station to communication data as per a cellular communications protocol. In one example, the mobile station includes different levels of memory to provide different deterministic access times.

The invention concerns a method () for employing adaptive event codes. The method includes the steps of generating () at least one adaptive event code in which the adaptive event code corresponds to a preexisting event code, storing () the adaptive event code in at least one table (), running () the table in which the adaptive event codes are at least initially disabled and enabling () the adaptive event code in response to a system event in which the preexisting event code that corresponds to the enabled adaptive event code is executed (). The method can further include the step of ignoring () the adaptive event codes during the running step when the adaptive event codes are disabled.

A method and apparatus for entering a low power mode is provided. In one embodiment, data processing system () has power control circuitry () which may be used to control power usage in data processing system (). Power mode select circuitry () may be used to select a power mode. Depending upon the power mode selected, power control circuitry () may use a cascaded approach to selecting which portions of data processing system () will be powered down, and thus how deeply data processing system () will be powered down.

A variable length decoder ( ) detects the class of a codeword in a bit stream ( ). If the codeword is first class, a first set of encoding rules are used to generate a pointer &ldquo;C A B&rdquo; into a table to retrieve table content ( ), where the values of &ldquo;C&rdquo;, &ldquo;A&rdquo;, and &ldquo;B&rdquo; are determined from the codeword. If the codeword is second class, a second set of encoding rules are used to generate a pointer &ldquo;0 (C&plus;X) Z&rdquo; into a table to retrieve table contents ( ), where the values of &ldquo;C&rdquo; and &ldquo;Z&rdquo; are determined from the codeword and the value of &ldquo;X&rdquo; is a predetermined value. The code length of each codeword is calculated while the pointer is being generated, and thus the code length does not have to be stored in memory ( ).
