    摘要: One block of non-zero coefficients obtained through the decoding of the entropy decoding unit 2024 is stored in the coefficient storage unit 121 in accordance with positional coordinates calculated by the non-zero coefficient scanning order calculation unit 2023a and the non-zero coefficient position conversion unit 2023b. The stored non-zero coefficients are then inverse quantized by the inverse quantization unit 2022. The non-zero coefficient range calculation unit 122 specifies a region of the coefficient storage unit 121 in which the non-zero coefficients are stored. The calculation order control unit 123 controls the inverse DCT unit 2021 to only perform an inverse DCT (discrete cosine transform) for non-zero coefficients located in the specified region.

    摘要: After power activation, a transferer 14 detects a bootstrap program 111 having a first error check code 114 assigned thereto and being stored in a first storage device 11, subjects the bootstrap program 111 to an error detection/correction process, and transfers the bootstrap program 111 to the second storage device 12. If the transfer is properly completed, by executing the bootstrap program 111 on the second storage device 12, the CPU 10 performs an error detection/correction process for a main program 112 having a second error check code 115 assigned thereto, and transfers the main program 112 to a third storage device 13, after which the CPU's control branches out to the main program 112 on the third storage device 13. As a result, system boot can be performed without employing a NOR type flash memory.

    摘要: A read process is performed on an ith designated block storing an ith divided data string. If the ith divided data string is not normally read, the read process is sequentially executed on ith ordinary blocks each storing the ith divided data string, where the ith ordinary blocks are included in ordinary block groups, respectively. When the ith divided data string is normally read, it is determined whether or not reading p divided data strings has been completed. If it is determined that the reading the p divided data strings has not been completed, the read process is performed on an (i+1)th designated block storing an (i+1)th divided data string following the ith divided data string.

    摘要: States of LSI internal signals (100 to 107) are monitored. Signal name information (31), signal state information (32), and information (33) about time in an LSI when a signal undergoes a state transition, are packetized and output as trace information (10) to the outside. In a development supporting device, the trace information (10) is decoded, the time information of the LSI is converted into real-time information, and based on the resultant information, a waveform of an LSI internal signal is reproduced. A plurality of LSI internal signals can be traced using terminals (16) the number of which is smaller than the number of the signals to be traced.

    摘要: An information processing device is provided in which a valid initial program is transferred to a RAM while avoiding a invalid block which is present in a low reliable storage device, such as a NAND-type flash memory or the like. A management information storing section 29 stores management information 30 indicating a position of a invalid block in a first storage device 31. When an information processing device 1 is powered on, a transfer determination section 20 is controlled to read a BSP 26 from a valid block of a first storage device 11 based on the management information 30, and transfer the BSP 26 to a second storage device 32. Thereby, it is possible to avoid reading of a invalid block present in the first storage device 31.
