    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.

    摘要: A data processor comprises a plurality of registers 1 (registers a to d), a plurality of data saving stack memory devices 2 coupled to the registers 1 for exclusive use thereof, respectively, and an instruction decoder for decoding instructions for controlling the registers 1 and the data saving stack memory devices 2 in accordance with the result of the instruction decoding. In response to an instruction "PUSH", the contents of the registers 1 (registers a to d) are selectively saved to the data saving stack memory device 2. In response to a instruction "POP", the contents of the data saving stack memory devices 2 are selectively restored to the registers 1 (registers a to d). Each of the instructions "PUSH" and "POP" has a field for indicating need or needlessness of the saving and restoration for each of the registers 1 and each of the data saving memories 2.

    摘要: A base station (5) comprises a base transmitter (6) for transmitting information optically to a plurality of portable stations (1 to 4) at such a predetermined time interval as is designated by portable station designating information. Each of the portable stations (1 to 4) comprises a potable transmitter (7) for transmitting information optically to the base station (5) in response to the transmission, which is designated by the portable station designating information coming from said base station (5), and within the range of the aforementioned time interval immediately after said transmission. Transmissions (ACK1 to ACK4) from the mating portable stations to the base station are individually inserted between the interval periods of the transmissions (REQ1 to REQ4) from the base station (5) to the portable stations (1 to 4) so that the single base station performs optical communications with the plurality of portable stations in a half-duplex time sharing manner.
