发明名称 Terminal apparatus
摘要 A low cost, a low power consumption and a small size are three very important factors for a mobile communication terminal. A great problem is posed by the conventional technique using a DSP and a CPU independent of each other which requires two external memory systems. Also, two peripheral units are required for data input and output of the DSP and CPU. As a result, an extraneous communication overhead occurs between the DSP and the CPU. The invention realizes a mobile communication terminal system by a DSP/CPU integrated chip comprising a DSP/CPU core ( 500 ) integrated as a single bus master, an integrated external bus interface ( 606 ) and an integrated peripheral circuit interface. The memory systems and the peripheral circuits of the DSP and the CPU can thus be integrated to realize a mobile communication terminal system low in cost and power consumption and small in size.
