<p>The present invention is a novel and improved method and appartus for performing multiple applications on a microprocessor or DSP. One embodiment of the invention includes a car kit for interfacing with a cellular telephone. The car kit includes a digital signal processor for performing digital signal processing and a cradle unit for holding the cellular telephone and for providing a link to said digital signal processor. Additionally, an on-chip memory is provided, located on an integrated circuit with the digital signal processor, for storing a limited function program that control said DSP. Off-chip memory stores multiple limited function programs and for laoding any one of the limited function programs to the on-chip memory.</p> |
