Preliminary
GENERAL DESCRIPTION
The ML87V3116 is a multi-function image processor LSI for small imaging devices.
Imaging functions, such as image input, temporary storage, processing and display output, are integrated into a
single chip. The ML87V3116 has functions includuing camera or video input image capture, display control in
LCD or TV format, compression and decompression of still pictures and moving pictures (Motion-JPEG) using a
JPEG engine, and image copying with the size reduction and the rotation.
DRAM is embedded inside the chip to improve the performance of memory access and realize simultaneous
operations of multiple functions. Furthermore, by adding external memory, large-sized images can be processed
and the moving pictures recording time can be extended.
