Abstract
A processor-based system such as a wireless communication module may implement security functions in a cost effective fashion by providing a virtual memory space whose addresses may be recognized. The memory is integrated with an application processor. When those addresses are recognized, access to special security protocols may be allowed. In another embodiment, a variety of dedicated hardware cryptographic accelerators may be provided to implement security protocols in accordance with a variety of different standards. By optimizing the hardware for specific standards, greater performance may be achieved.
