    Abstract: The present invention is provided to lessen load on a bus in the case of storing image data captured by a plurality of cameras into a semiconductor memory. To a semiconductor integrated circuit, a plurality of cameras and a semiconductor memory can be coupled. The semiconductor integrated circuit includes a plurality of first interfaces, a second interface, a bus, and a plurality of image processing modules. The image processing modules include a process of performing distortion correction on image data in a pre-designated region, and writing the image data in the region subjected to the distortion correction into the semiconductor memory via the bus and the second interface. By excluding image data out of the pre-designated region from an object of distortion correction in the image processing modules, the amount of image data transferred to the semiconductor memory is reduced.

    Abstract: An ATM cell processing apparatus including a DRAM for a frame producing buffer of a frame producing unit. In order to absorb the anisotropy of the access rate of the DRAM access, the random access mode of the DRAM access is always used. To compensate a drop in access rate in this case, the DRAM is arranged is an array form and each cell is divided. Resultant partial cell data are written into and read from respective DRAM banks in order. As a result, a fast cell buffer having a large capacity can be formed. The present cell buffer can be applied to a FIFO and the like as well.

    Abstract: This invention relates to an information processing apparatus such as a digital signal processor and is applied particularly suitably to a digital filter.A plurality of data from initial value data till final value data relating to filtering coefficients of a digital filter are stored in a data memory, and are sequentially read out by an increment operation of an address arithmetic unit.A data arithmetic unit executes sequentially product and/or sum operations of a plurality of data that are sequentially read out and digital input signals that are sequentially inputted, to perform digital signal processing.The information processing apparatus is equipped particularly with means, which when an access address starts from an initial value, exceeds a final value and reaches a return address due to the increment operation, returns automatically the access address to the initial value. Therefore, a plurality of data stored in the data memory can be utilized repeatedly.Contrivances are made in order to set the number of a plurality of data that are stored in the data memory for repetition of use, to an arbitrary value.

    Abstract: This data processor can satisfy both requests of a fast transition from a low power consumption state to an operating state and low power consumption, and a data processor has a program running state, a standby mode, a light standby mode, and a sleep mode. In the sleep mode, the supply of a synchronizing clock signal to a central processing unit (CPU) is stopped and the synchronizing clock signal is supplied to other circuit modules. In the standby mode, the frequency multiplication and frequency operation of a clock pulse generator are suspended and the supply of the synchronizing clock signal to the CPU and other circuit modules is stopped. In the light standby mode, the frequency multiplication and frequency division operation of the clock pulse generator are enabled and the supply of the synchronizing clock signal to the CPU and other circuit modules is stopped. In the light standby mode, the transition of the CPU to an instruction executable state is faster than in the standby mode and the lower power consumption than in the sleep mode is obtained.

    Abstract: In order to simplify the instruction prefetch architecture for use with the programs having few loops, and having instructions almost in linear and sequential addresses, the bus controller in accordance with the present invention for controlling the bus in an external memory includes a plurality of instruction buffers, flags each specific to each of instruction buffers, and a buffer controller circuit. The buffer controller circuit may allocate one of specific values that plural lower bits of an instruction address may take to each of the instruction buffers, and prefetch instructions to the instruction buffers each corresponding to a respective addresses designated to by the plural lower bits, from the address following a predetermined fetch address. The constitution for instruction prefetch as above may be implemented in a simpler manner than the controlling structure using address tags of a cache memory or the controlling structure using read-write pointer based on the counter in FIFO buffers.
