摘要:
Provided are a microprocessor suitable for constructing a multi-processor system and a method for controlling the reset and processor ID of the microprocessor. The microprocessor includes decoder receiving a reset ID having a predetermined binary value and a reset signal and decoding the reset ID, an ID generator receiving the decoding result of the decoder and generating at least one microprocessor ID and a reset ID of a microprocessor serially connected to the microprocessor, and a reset vector unit selecting a reset vector according to the decoding result of the decoder. The multi-processor system is constructed such that independent microprocessors of the system respectively generate their own reset vectors and processor IDs when a reset signal is input to the multi-processor system to initialize it. Thus, all the microprocessors of the system can be simultaneously started up when the reset signal is disabled. Accordingly, a resetting process in the multi-processor system is simplified, a period of time required for starting up the microprocessor is reduced, and the multi-processor system is easily designed.

A method for converting an IBIS (Input/output Buffer Information Specification) model to a SPICE (Simulation Program with Integrated Circuit Emphasis) behavioral model by RC (resistor/capacitor) extraction is provided. In the method, when the SPICE behavioral models of pull-up and pull-down transistors being switching components of the output IBIS model is embodied, a resistance is extracted from voltage-current tables of the pull-up and pull-down transistors and a capacitance is extracted from voltage-time tables of the pull-up and pull-down transistors so that a static characteristic is modeled as a resistor and a dynamic characteristic is modeled as a capacitor.

A system and a method are provided to execute a bi-directional character transfer between portable communication devices to share information and functions thereof. After one of first and second devices is recognized in the other device, a character stored in the first device is transferred to the second device. Then the transferred character is driven in the second device. First information stored in the first device may be transferred with the character. The first information is then extracted from the character in the second device. The character may be transferred from the second device to the first device. Second information produced by operation of the character in the second device may be transferred with the character to the first device, and extracted from the character in the first device.
