Title: Interrupt-processing system for shortening interrupt latency in microprocessor
Inventor: YANG PACHINCO
IPC: G06F13/24
Filed: 2003-03-07
Abstract: This invention relates to a data processing system comprising a memory module and a microprocessor. The memory module comprises at least a low-speed memory and a high-speed memory, both storing an interrupt vector table for recording the entrance instruction of interrupt service routines. The microprocessor comprises a central processing unit (CPU) and a memory controller with a re-addressing device. Once an interrupt occurs, the CPU generates and transmits an interrupt vector address to the memory controller. If the vector is located in the range of interrupt vector table, the re-addressing device sends an enable signal to the high-speed memory to enable the CPU to fetch the entrance instruction of interrupt service routine from the high-speed memory, not from the pre-determined low-speed memory. Hence, the interrupt latency is reduced.

Title: Writable recording medium, recording method for identification data, data recording device, playing method of identification data, and data playing device
Inventor: SAKO YOICHIRO
IPC: G11B20/00
Filed: 2003-03-18
Abstract: The present invention provides the writable recording medium which can be easily determined if they the formal or the copied disks, the recording method of identification data, the data recording device, the playing method of identification data, and the data playing device, which can be easily determined if they are the formal or the copied disks. The method is to read the first disk ID played in the program memory area (PMA) and the second disk ID recorded during playing in the playing program area (PA). When the two IDs are identical, the disk will be determined as a formal disk; otherwise, it will be determined as a copied disk. Because the original disk ID was recorded in PMA during the disk initialization process, the disk IDs in the formal or the copied disks will be different originally. By using the difference as the disk determination information, the present invention can realize the determination by previously recording the disk ID of the formal disk in the PA.

Title: Noise reduction method of filter
Inventor: HWU KEH-LONG
IPC: H03H9/54
Filed: 2003-12-30
Abstract: A noise reduction method of filter is used to eliminate the standing wave signal interference in the acoustic filter formed by plural thin film bulk acoustic resonators (FBARS) and the abnormal signal resulted from the lateral high-frequency harmonic resonance. The method is to dispose plural interfering structures in the structure formed by the FBARS. The different characteristics of the material result in an energy band gap structure, so as to generate a destructive interference to the lateral high-frequency harmonic resonance in a specific range of operating frequency, and further reduce or even eliminate the parasitic effect. Therefore, in the range of operating frequency of this energy band gap structure, the abnormal signal resulted from any abnormal lateral modes cannot exist. In addition, the phononic crystal structure between different piezoelectric film resonators can also form an acoustic shield, so as to prevent the mutual interference in the range of operating frequency.
