Patent TW-413782-B (TW)
Title: Signal fetch method and device for digitizing board
Inventor: LI WEN-JIN
IPC: G06F3/033
Filed: 1999-03-12
Granted: 2000-12-01
Abstract: The invention provides a signal fetch method and device for digitizing board, in which the pointer pen positions the coordinate location on the antenna loop of the digitizing board. The antenna loop that can be separated into the front half section and the back half section in terms of working area and multiplexing array circuit for fetching the pointing signal emitted by the pointer pen are the major parts. After the pointing signal of the pointer pen is processed by an amplification circuit, a phase selection circuit chooses proper phase from the fetched location of the pointer signal, either the front half section or the back half section, allowing the pointer signal in the same antenna loop to have different first half signal and back half signal. The occurrence time of negative direction zero-crossing signal obtained via signal processing circuit is further converted to the coordinates data of digitizing board by means of microprocessor computation to form the signal fetch method and device of the digitizing board. Thus, the internal electronic components of the multiplexing array circuit can be reduced. Moreover, the effect of simplifying the assembly and cost-down can be secured. The improvement targeting at wired and wireless digitizing board ensures the fetching of correct pointing signal and more complete functionality.

Title: Data switching system and method using bandwidth management unit to reduce data traffic
Inventor: HOU CHIEN-TZU
IPC: G06F13/16
Filed: 1999-08-26
Granted: 2001-08-01
Abstract: A system and method for reducing data traffic between the processor and the system controller in a data processing system during the execution of a vector or matrix instruction. When the processor receives an operation command requiring that a large quantity of data be processed, the processor issues a local operation request containing the desired operation, addressing information of the operands and a destination location for the result to the system. The system controller includes a local operation unit for locally executing the local operation request issued from the processor. Because the operand data associated with the operation need not be transferred over the system bus connected between the processor and the system controller, the data traffic between the processor and the system controller is reduced.
