Frame buffer has four data ports

Logic Devices Inc. disclosed that it has begun sampling its LF3312 frame buffer/First-In First-Out (FIFO). This new device promises designers with the most flexible memory solution to buffering multiple video formats, using both sequential and random access.

By integrating both high-density 12Mb memory and advanced addressing control logic, the LF3312 simplifies the design of current video and data buffering systems typically using standard SRAM paired with FPGA logic. The LF3312 features up to four data ports and several addressing modes, allowing the memory to be accessed sequentially, through random access, or both. Logic Devices added that the product's flexible addressing allows the device to perform FIFO, shift register, synchronization and mixed sequential/random access functions. With just over 12.4Mb of memory and a maximum data rate of 83MHz, the LF3312 can buffer multiple video formats.

The LF3312 is mainly targeted towards security surveillance systems, broadcast video equipment, medical imaging, machine vision and video editing systems. The device configurability, along with its 83MHz operating speed, provides the designer with unprecedented flexibility in numerous applications that require storage density, speed, and flexible addressing. The FIFO and Shift Register modes are useful in synchronizing multiple video streams or data feeds, frame synchronization, motion detection, scan rate conversion, motion adaptive de-interlacing and time base correction. The Random Access modes facilitate complex addressing schemes such as multi-queue buffering, video compression algorithms, image rotation, area of interest and picture in picture (PIP) extraction.

The LF3312 is packaged in a 15-by-15mm small form factor 172-pin Low Profile Ball Grid Array (LBGA) package. The package will be available in a Pb-free version. Commercial temperature grade production samples of the LF3312 are already available, with initial pricing for the LF3312 set at $25 each in quantities of 10,000.
