    摘要: In accordance with a rate detecting method for detecting a predetermined rate at which a received signal has been coded, the coded signal is decoded based on a first synchronizing signal having a frequency corresponding to a first rate such that a first decoded signal (ST11) is generated and then it is judged whether or not synchronization is determined for the first decoded signal (ST12). If the synchronization cannot be determined, there is generated only a second synchronizing signal having a frequency corresponding to a second rate having a difference between itself and a first rate which is smaller than a permissible value of the rate determined by the lower and upper values of the rate (ST13, ST17).

    摘要: Logic circuits access a memory block by way of an access circuit. The memory block, which is formed of a mixed configuration of DRAMs and an SRAM, realizes the desired memory space. A data output register is provided at the output side of the SRAM so as to synchronize data output timing from the DRAMs with data output timing from the SRAM.

    摘要: A plurality of logic circuits access a DRAM block by way of an access circuit. The operation clock for the DRAM block is set at a higher frequency than the system clock for the logic circuits. Outputs of a first bit width from the logic circuits are subjected to serial/parallel conversion into data of a second bit width and the data is written into the DRAM block.
