3.1.5 General Description
Figure 3-1-2 depicts the block diagram of MT6235. Based on a dual-processor architecture,
MT6235 integrates both an ARM926EJ-S core and a digital signal processor core. ARM926EJ-S
is the main processor responsible for running high-level GSM/GPRS protocol software as well as
multi-media applications. The digital signal processor manages the
low-level MODEM as well as advanced audio functions. Except for a few mixed-signal circuitries,
the other building blocks in MT6235 are connected to either the microcontroller or the digital
