2 / 2 page Driving the Digital Lifestyle Driving the Digital Lifestyle PM-36 Capabilities The PM-36 enables the following combinations of operations to be performed on the data stream during one pass through the device: • Raster format image data: Converted to Block mode, subsampled 2:1, and JPEG encoded • Block format image data: JPEG encoded • JPEG-encoded data: JPEG decoded to raw format, upsampled 2:1, and output in Block or Raster format Design Considerations The PM-36 can be easily integrated into a variety of systems. Design features include: • A simple peripheral interface for use with any standard processor • Programmable control port bus width (16 or 32 bits) • Flexible input and output ports, which simplify system design • Input and output ports can be sized at 8, 16, 24, or 32 bits wide and contain bit, byte and word order controls to match any processor bus requirements • 256-byte buffer on both input and output ports can minimize or even eliminate external buffering requirements • High speed I/O modes, synchronous FIFO and Burst DMA modes The PM-36 requires little in the way of external support chips. A minimal system requires only a frequency source. An external SRAM array (up to 4 MB) may be added to enable raster format data streams. The external SRAM is used to store input or output lines for raster-to-block or block-to-raster conversion operations PM-36 Specifications Formats Supported • Grayscale pixels in Raster or Block format (8 bits per pixel) • Color pixels in Raster or Block format (8 bits per component) • JPEG-encoded data Electrical Specification • 3.3 Volt power supply • 5 Volt tolerant I/O (TTL-compatible I/O) • Designed and fabricated in 0.35 micron standard cell technology • Available industry-standard 208 PQFP package with 0.5 mm lead spacing • Also available in lead-free “green” packaging 01/06-MMCP Imaging-PM-36-PB-1.2 PM-36 JPEG Image Processor Product Brief Descriptions (continued) PM-36 Block Diagram I/O Interface Input/Output FIFO Data In 8/16/24 or 32 bit © Copyright 1999-2006 Zoran Corporation.
