SYSTEM-ON-CHIP AND APPLICATION PROCESSOR INCLUDING FIFO BUFFER AND MOBILE DEVICE COMPRISING THE SAME

摘要

A system-on-chip according to the present invention includes a data producer block; an FIFO buffer which stores data transferred from the data producer at a memory area corresponding to a write pointer; a first consumer block which pops data of a memory area corresponding to a first read pointer of the FIFO buffer out; and a second consumer block which pops data of a memory area corresponding to a second read pointer of the FIFO buffer out. The FIFO buffer requests a pop-out operation to the second consumer block according to the difference between the write pointer and the first read pointer or overwrites the data provided from the data producer block at the memory area corresponding to the second read pointer.
