| abstract |
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. |
