摘要:
A routing switch for constructing an interconnection network of a parallel processing computer is disclosed. A purpose of the present invention is to provide a crossbar routing switch for a hierarchical interconnection network which has an expandability of a data length and an expandability of a hierarchical structure. The crossbar routing switch for a hierarchical interconnection network in accordance with the present invention comprises a predetermined number of input control units for controlling one input port to perform the manipulation of input data; a crossbar core unit for analyzing a data transmission request by the input control unit and outputting the corresponding data; and a predetermined number of output control unit for controlling one output port and receiving the output data from the crossbar core unit to output it to the output port. The present invention has advantages over the prior art that a data expandability can be provided by simply adding a routing switch without re-designing or re-manufacturing the routing switch several times, and that it can be suitably adapted to an interconnection network of a parallel processing system which requires a high expandability and high performance.

The present invention relates to a hierarchical crossbar inter-connection network for a cluster-based parallel processing computer. A crossbar network is composed of the "n" number of crossbar switches which is byte sliced, eight links for connecting eight nodes, and two links for connecting other clusters. In addition, one low-level cluster is formed by connecting a maximum of eight processing nodes between the two crossbar networks, and one high-level cluster is formed with a maximum of eight low-level clusters and the four crossbar networks. Moreover, one next high-level clusters formed with a maximum of eight high-level clusters and the eight crossbar networks for scalability.

In a first-in first-out memory circuit using a standard cell library memory, a memory block includes N number of memories (N>1). A read pointer designates read addresses of the N number of memories. A write pointer designates write addresses of the N number of memories. A memory controller selects one from the N number of memories based on the read/write addresses, generates n number of read/write clock signals by demultiplying a clock signal by n (n=N, n>1) and sends the n number of read/write clock signals having a 1/n cycle difference to the N number of memories thereby inputting/outputting data.

A radio frequency identification (RFID) tag based object position tracking apparatus and method are provided. The apparatus includes a position recognizer including at least one radio frequency identification unit for reading information data on an object through a sensor; and a path analyzing and processing unit for allocating each unique coordinates to the radio frequency identification units based on a relative position in a space where a position recognizer is disposed and recognizing the position of the object and analyzing the path based on the object information data received by the sensor in the radio frequency identification unit corresponding to the unique coordinate. Thus, it is possible to track the path of an object with a low density of RFID tags.

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.
