Frame buffer

摘要

A frame buffer exhibits a serial/parallel converter in order to convert serial input data into parallel data, a first latching device for latching the parallel data from the serial/parallel converter, a data buffer for storing parallel data which were output by the first latching device, a second latching device for latching parallel data which were read out from the data buffer, a parallel/serial converter for converting parallel data, which were read out at the second latching device, into serial data, an address generator for supplying a write address and a read address to the data buffer on a time-division basis, and an address control device for controlling the address generator.
