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:
Design Considerations
The PM-36 can be easily integrated into a variety of systems.
Design features include:

• Raster format image data: Converted to Block mode, subsampled
• Block format image data: JPEG encoded
• JPEG-encoded data: JPEG decoded to raw format, upsampled
• A simple peripheral interface for use with any standard processor
• Programmable control port bus width (16 and 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
• 256-bytes buffer on both input and output ports can minimize or
• 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
2:1, and JPEG encoded
2:1, and output in Block or Raster format
and contain bit, byte and word order controls to match any
processor bus requements
even eliminate external buffering requirements
