CYFB0072V 72-Mbit Video Frame Buffer 72-Mbit Video Frame Buffer Features ■ Functional Description The Video Frame Buffer is a 72-Mbit memory device which operates as a FIFO with a bus width of 36 bits. It has independent read and write ports, which can be clocked up to 133 MHz. The bus size of 36 bits enables a data throughput of 4.8 Gbps. The device also offers a simple and easy-to-use interface to reduce implementation and debugging efforts, improve time-to-market, and reduce engineering costs. This makes it an ideal memory choice for a wide range of applications including video and image processing or any system that needs buffering at high speeds across different clock domains. The functionality of the Video Frame Buffer is such that the data is read out of the read port in the same sequence in which it was written into the write port. If writes and inputs are enabled (WEN & IE), data on the write port gets written into the device at the rising edge of write clock. Enabling reads and outputs (REN & OE) fetches data on the read port at every rising edge of read clock. Both reads and writes can occur simultaneously at different speeds provided the ratio between read and write clock is in the range of 0.5 to 2. Appropriate flags are set whenever the device is empty or full. The device also supports a flow-through mailbox register to bypass the frame buffer memory Memory organization ❐ Density: 72-Mbit ❐ Organization: × 36 Up to 133-MHz clock operation [1] Unidirectional ...
