Title: Data writing device and computer-readable storage medium
Inventor: YASUKI HIROYUKI
IPC: G06F12/06
Filed: 2000-08-21
Abstract: PROBLEM TO BE SOLVED: To accurately recognize a mounting part, where a ROM(read only memory) exists, in a data writing device for writing data into the ROM. SOLUTION: A device code stored in a flash ROM on a PCB is required (S1), and it is determined whether the ROM is present in its mounting part (S2). Based on this determination, erasure work is started on the mounting part mounted with the PCB (S3). Since the device code is stored in the ROM, if the ROM is not present, the device code cannot be received. Accordingly, it can be recognized accurately as to whether the ROM exists, without having to determine that 'ROM exists' relative to the mounting part, when the ROM is not present there.

Title: Sampling rate converter
Inventor: KANEAKI TETSUHIKO
IPC: H03H17/00
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To provide an asynchronous sampling rate converter that operates stably with high accuracy even when the converter receivers a clock signal including jitter. SOLUTION: A PLL circuit 3 multiplies the sampling rate of input data to generate a clock signal fx for frequency ratio measurements and to generate an end flag flock denoting that the multiplication operation is locked. A frequency ratio detector 4 detects the ratio of the sampling rate of the clock signal fx to that of an output signal. A delay unit 5 and a comparator 6 are used to detect fluctuations in frequency ratio data and instruct a sampling rate conversion section 2 to start its operation when the fluctuations are within a prescribed range. In this case, by changing a permissible fluctuation range of the frequency ratio directly after the end flag flock is set and that of the frequency ratio in a steady-state, the effect of jitter included in the clock signal fx can be suppressed.
