摘要： A GALS-based network-on-chip (NoC) includes a plurality of asynchronous first-in first-out (FIFO) input buffers connected to a plurality of IPs that asynchronously receive data; a plurality of asynchronous FIFO output buffers connected to the plurality of IPs asynchronously output data; and a router for forwarding data input to the plurality of asynchronous FIFO input buffers, to an asynchronous FIFO output buffer, among the plurality of asynchronous FIFO output buffers, which is connected to an IP to which the data is destined. Accordingly, the system-on-chip (SoC) adopting the GALS design scheme can transfer data via the NoC between the IPs which are in time zones having different clocks in the centralized switching system, thereby avoiding the need for a point-to-point system.

摘要： An input buffer device and control method of the input buffer device. The input buffer device includes a virtual output queuing (VOQ) buffering section which has a plurality of VOQ buffers. The input buffer device stores data which is input to an input port to a VOQ buffer corresponding to an intended output port of the data among the plurality of VOQ buffers. A shared buffering section is provided which stores the data when a VOQ buffer corresponding to the intended output port of the data is full of data. The stored data is forwarded to the VOQ buffer when the VOQ buffer is empty. Accordingly, the input buffer device can more efficiently process the data by use of the fixed-length FIFO buffers and the shared buffer.

摘要： A method of modulating data, which is represented by two data types of ‘high’ and ‘low’, and demodulating the modulated data, is disclosed. In a method of data modulation and demodulation for a communication system which has a transmitting end modulating a data and a receiving end demodulating the transmitted data from the transmitting end, the data is represented by two types including ‘high’ and ‘low’, and the receiving end receives at least one data which consists of at least one code-word spread by a unique orthogonal code. The receiving end adds up the received data in the unit of code-word, and subtracts the length of the orthogonal code from a value which is obtained by doubling the sum of the code-word, when the code-word of the orthogonal code is ‘0’. The receiving end then averages the result after the subtraction in the unit of orthogonal code length and e-tracts the result, and therefore obtains the data from the transmitting end.
