Stand-alone IP for Pre-/Post-processing

Chips&Media MAPI is a high-resolution Image Processing IP. It is capable of scaling up/down and color space conversion on a frame-by-frame basis with various input and output image formats.

The MAPI features its flexibility with a range of supported interfaces for data transmission. Image data can be transmitted without DRAM access via display or direct interface. Also, they can be read and written to/from the main memory via the AMBA3 AXI interface. MAPI can be used as a pre-processor for video encoder or as a post-processor for video decoder.

​

Performance

• 4K60p@400MHz (600MHz for display interface)

​

Features

• Support various color format : YUV420, YUV422, YUV444, and RGB

• Up-/Down-scaler x1/8~x8 : selectable scaler algorithm with Bi-cubic and Lanczos

• Two scalers, connected to DRAM and display/direct I/F respectively, operating at different ratios at the same time                      (configurable to one scaler option)

• Color space conversion : YUV2RGB and RGB2YUV, coefficient downloadable

• Optional features

  • Crop and digital zoom : scaling on cropped region

  • Flip : horizontal and vertical

  • 3rd Party interfaces: such as AFBC v1.2 and PVRIC v4 (support output only)

​

Interface​

• Display Interface : 3 channels for components with vertical/horizontal sync signal (ITU-R BT.601 compatible)

• Direct Interface (optional feature) : On-the-fly interface based on ready-valid protocol

• Support CF10 (Chips&Media’s Frame buffer compression) for Chips&Media video codec

• Support AFBC v1.2 and PVRIC v4 (optional feature) for output of MAPI
