CELLULAR TELEPHONE APPARATUS |
摘要 |
<p>A cellular telephone apparatus in which several functions such as decoding and encoding data signals, detecting the busy/idle bit and transponding the SAT signal, are carried out by a CMOS data processor (20) which is separate from a CMOS micro-controller (34). The data processor (20) can be operated at a lower clock frequency (1.2 MHz) than the micro-controller (34) which enables current to be saved compared to processing these functions in software using the micro-controller.</p> |
