Mobile wireless communications device providing data management and security features and related methods
First Claim
1. A mobile wireless communications device comprising:
- a wireless transceiver;
a series of processing modules;
a shared memory connected to said processing modules and to said wireless transceiver;
a memory manager module for generating data location indices for data stored in said shared memory;
said processing modules cooperating with said shared memory and said memory manager module so that an upstream processing module stores given data in said shared memory and so that a downstream processing module receives the data location index for the stored given data and processes the stored given data based thereon; and
a security module for selectively purging data from said shared memory.

Abstract
A mobile wireless communications device may include a wireless transceiver, a series of processing modules, a shared memory connected the plurality of processing modules and to the wireless transceiver, and a memory manager module for generating respective data location indices for data stored in the shared memory. The processing modules may cooperate with the shared memory and the memory manager module so that an upstream processing module stores given data in the shared memory, and so that a downstream processing module receives the data location index for the stored given data and processes the stored given data based thereon. The device may further include a security module for selectively purging data from the shared memory.
