PM-36中文资料卓然数据手册PDF规格书

The PM-36 is a fixed-function Codec device that delivers high speed JPEG compression/decompression of color and grayscale image data. An ISO standard for lossy image compression, JPEG can reduce the size of image data without a noticeable difference in image quality. This improves system performance of peripheral-based applications by reducing bandwidth and storage requirements. The PM-36 is ideal for high resolution imaging applications such as copiers, scanners, printers and multifunction peripherals, particularly in networked environments.

Key Features

• Conforms to ISO IS 10918-1/10918-2 JPEG baseline for grayscale and color

• 80 MHz clock speed for sustained 80 MB/second throughput (Raster or Block mode operations)

• 110 MHz clock speed for sustained 110 MB/second throughput (Block mode operations only)

• 3.3 Volt power supply

• Four selectable quantization tables

• Two pairs of loadable Huffman tables

• Programmable code rate control

• Programmable code size control (single pass)

• Raster and block data formats

• Internal 256-byte buffers on input and output ports

• I/O modes supporting transfer rates up to 40 MHz (280 MB/per second)

• Internal Phase-Locked Loop (PLL)

• Horizontal 2:1 subsampling and upsampling support for 4:2:2 formats using 2 or 3 point filters (Raster mode operations only)
