LF48908JC25 Datasheet PDF - LOGIC Devices

DESCRIPTION
The LF48908 is a high-speed two dimensional convolver that implements a 3 x 3 kernel convolution at real-time video rates. Programmable row buffers are located on-chip, eliminating the need for external data storage. Each row buffer can store up to 1024 pixels. Two internal register banks are provided allowing two separate sets of filter coefficients to be stored simultaneously. Adaptive filter operations are possible when both register banks are used. An on-chip ALU is provided, allowing real-time arithmetic and logical pixel point operations to be performed on the image data.
