Title: Interface apparatus and method of digital signal processor in adsl modem
Inventor: KIM CHUNG RAE
IPC: G06F13/00
Filed: 1998-11-18
Abstract: PURPOSE: To provide apparatus and method capable of interfacing a digital signal processor in long mode cycle by using internal direct memory access(IDMA) port interface. CONSTITUTION: A host processor checks an IDMA port access ready acknowledge signal(/IACK) in a digital signal processor(DSP). If the /IACK is enabled, the processor sends an IDMA port address latch enable signal(IAL) and an IDMA port selects signal(/IS) to the DSP, and then transmits a start address and an end memory type information to the DSP through an IDMA port address/data bus. An address latch cycle is performed according to such process. In data write to the DSP, the processor sends the /IS and an IDMA port write signal(/IWR) so that the DSP writes the data to a location indicated by a target IDMA address. The processor drives the data to write when the /IACK is disabled, and then stops writing operation when the /IACK is again enabled. Like this, a long write cycle is performed. In data read from the DSP, the processor sends the /IS and an IDMA port read signal(/IRD) so that the DSP loads the data to a location indicated by the IDMA address, and then reads the data loaded on the IDMA port address/data bus when the /IACK is changed from disable to enable. Thereby, a long read cycle is performed.

Title: Circuit for generating dead time signal in a servo driver
Inventor: CHO YOU HWAN
IPC: H02P27/08
Filed: 1998-12-31
Abstract: PURPOSE: A circuit for generating the dead time signal is provided to protect the power switching devices of a servo driver or an inverter from surge. CONSTITUTION: A servo driver comprises a PWM generating circuit, a dead time generating circuit(20), and a gate driving circuit. When the power switching devices connected in series are turned on simultaneously then the over-current destroys them. A dead time generating circuit(20) has dip switches(24) setting the initial value and a binary counter(23) counting the delay time. The counter produces a carry out signal based on the reference clock. The carry out signal from a NOT gate is reversed and becomes a delay time. A D-flip-flop(22) receives a delay time through clock path and generates the delayed PWM signal. An AND gate generates a gate control signal UPPER_A to drive the power switching device and a NOR gate generates a gate control signal LOWER_A to drive the power electronic device, so the circuit prevents the devices to be shorted.

Abstract: PURPOSE: A method for encoding transmission information is provided to improve the reliability of authentication process as a radio telecommunication company and an authentication institute provide encoded information in case that a subscriber requests a service and execute authentication process for information transmitted from the subscriber sequentially. CONSTITUTION: If a subscriber selects a money charging mode, a radio telecommunication company informs the subscriber to input a password, a count value and desired charging money as voice messages. The company compares whether the password inputted by the subscriber is the same one as a previously registered password. If both passwords are the same, the company compares whether the present input count value is larger than a previous input count value. If the present input count value is larger than the previous input count value, the company transmits the subscriber's account number to a bank and requests the bank to confirm whether enough money for desired charging money has been deposited in the subscriber's account. The bank inquires whether enough money for desired charging money exists in the subscriber's account and transmits a result to the company.
