摘要： The data processor enhances the bus throughput or data throughput of an external memory, when there are frequent continuous reads with a smaller data size than the data bus width of the external memory. The data processor includes a memory control unit being capable of controlling in response to a clock an external memory having plural banks that are individually independently controllable, plural buses connected to the memory control unit, and circuit modules capable of commanding memory accesses, which are provided in correspondence with each of the buses. The memory control unit contains bank caches each corresponding to the banks of the external memory. Thereby, the data processor enhances the bus throughput or data throughput of the external memory, since the data processor stores the data read out from the external memory temporarily in the bank caches and to use the stored data without invalidating them, when performing a continuous data read with a smaller data size than the data bus width of the external memory.

摘要： An electronic circuit includes a first semiconductor device and a second semiconductor device on a mounting substrate. The mounting substrate lines have lengths which are made unequal for respective bits. Assembling lines which reach connecting electrodes of a semiconductor chip from the external terminals of the second semiconductor device have made lengths thereof unequal for respective bits. The unequal lengths of the mounting substrate lines have a relationship which offsets the unequal lengths of the assembling lines.

摘要： It is aimed at providing a data processor capable of suppressing a sudden current change from the viewpoint of a synchronization clock. A data processor 1 comprises a clock pulse generation circuit and a circuit module operating on input clock signal CLKi output from the clock pulse generation circuit. In case of restoration from a power-on reset period or a standby state, the clock pulse generation circuit stepwise changes frequencies of the clock signal from low to high frequencies. This makes it possible to prevent a power supply current from suddenly increasing in case of restoration from the power-on reset period or the standby state.

摘要： A temperature sensor in a semiconductor device includes a temperature detection circuit for outputting a voltage according to the chip temperature, a reference voltage generating circuit for generating a plurality of reference voltages, and a plurality of voltage comparators for comparing each reference voltage with an output voltage of the temperature detection circuit and thereby generating a chip temperature detection signal configured with multiple bits. Further, the temperature sensor includes a control circuit for controlling the reference voltages generated by the reference voltage generating circuit based on the chip temperature detection signal and thereby changing correspondence between the chip temperature detection signal and the chip temperature to shift a chip temperature detection range. It is possible to expand the chip temperature detection range by changing the correspondence between the chip temperature detection signal and the chip temperature, without increasing the number of voltage comparators.
