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.

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 processor which executes positive conversion processing, which converts coded data into uncoded data, and saturation calculation processing, which rounds a value to an appropriate number of bits, at high speed. When a positive conversion saturation calculation instruction “MCSST D1” is decoded, the sum-product result register 6 outputs its held value to the path P1. The comparator 22 compares the magnitude of the held value of the sum-product result register 6 with the coded 32-bit integer “0x0000_00FF”. The polarity judging unit 23 judges whether the eighth bit of the value held by the sum-product result register 6 is “ON”. The multiplexer 24 outputs one of the maximum value “0x0000_00FF” generated by the constant generator 21, the zero value “0x0000_0000” generated by the zero generator 25, and the held value of the sum-product result register 6 to the data bus 18.
