摘要： The present invention provides a CPU-containing LSI in which software stored in an external memory is incorporated partially into a RAM and thereby the capacity of the RAM to be used can be held down, and an optical disk device including the same. In the CPU-containing LSI, the RAM includes a software storage region where software read in from the external memory on a module-by-module basis is stored, and an entry table in which entries are stored, with the entries each containing at least information as to a location and a size of a module stored in the software storage region. The CPU refers to the entry table to decide the location where a module to be read in from the external memory to the software storage region is to be stored, according to an incorporation-location search program.

摘要： A device for encoding an error correcting code for input data of natural number N bits per symbol, by using a Reed-Solomon code having elements on a Galois field GF(2.sup.N) having a number of elements of 2.sup.N. The ROM (14) is provided as product data storage device, after previously computes a plurality of product data on the Galois field between each of the input data and each of coefficients of a generator polynomial of the Reed-Solomon code, and the ROM (14) previously stores the plurality of product data with handling a plurality of b product data as one set for each address. The read control device (12, 13, 24-26, 28), in response to the input data, read out the plurality of product data stored in the ROM (14) in parallel with the plurality of b product data taken as one set, and thereafter write them selectively and sequentially into the natural number m storage units (20-22) via the exclusive OR computing units (15-18) and the bus selector (19). Input data is inputted to the ROM (14) sequentially, and then parity data are generated by the m storage units and outputted therefrom.

摘要： There is provided an optical disc device including an objective lens, a lens actuator for driving the objective lens, a light-receiving unit, and a system control unit which determines, at startup, the values of parameters to be set for recording or reproducing data in or from the respective information layers, and performs setting and management of recording inhibition or reproduction inhibition for the respective information layers, wherein, even when an error occurs because the values of the parameter groups for the respective layers cannot be determined in an optical disc having laminated plural information layers, recording or reproduction can be performed for at least the layers for which the parameters can be correctly determined, without stopping the startup. Thereby, the states of the respective information layers are managed for each information layer, and reproduction or recording operation is rapidly started in the respective layers to effectively utilize the multilayer disc.

摘要： A recording medium for storing a data stream is comprised of first error correcting codes obtained by encoding first information, second error correcting codes obtained by encoding second information, and synchronization signals. In the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. The second error correcting codes have the same number of corrections as the first error correcting codes. A code length of the second error correcting codes is shorter than a code length of the first error correcting codes.

摘要： A digital modulation apparatus capable of generating a modulated code so that binary slice is correctly performed when reproducing is provided. To achieve this, in a digital modulation apparatus (10A), a DSV change amount calculator (15) calculates change amounts (ΔDSVa, ΔDSVb) in DSVs of candidate modulated codes (CODEa, CODEb) generated by a modulated code generator (11). A modulated code determinator (13) compares the change amounts (ΔDSVa, ΔDSVb), and determines that the candidate modulated code having a smaller absolute value should be selected as a modulated code (CODE). A modulated code selector (14) selects one of the candidate modulated codes (CODEa, CODEb) which is determined by the modulated code determinator (13), and outputs the selected code as a modulated code (CODE) for source data (DATA).

摘要： When recording is carried out in a DVD-RAM, if at least one address mark could have been detected at the header section, after a test light emission for a laser power control is carried out at a GAP section, normal recording is carried out from GUARD1. Herein, if the delay time in the reproduced data would have increased, and if the head of the GAP section has been passed by at the timing when the AM4 is detected in a period during judging whether the fourth AM has been detected or not, it would not be possible to carry out a test light emission normally at the GAP section. In an optical disc recording device of the present invention, when any of the first to third address marks could have been detected, a test light emission is carried out at the GAP section as conventional, and normal recording is carried out from GUARD1 with controlling the laser powers on the basis of that result. When only AM4 could have been detected, the test light emission is not carried out and normal recording from GUARD1 is carried out.
