The Camera Interface Subsystem is based on CAL (Camera Adaptation Layer) module and up to two MIPI D-PHY compliant receivers.
CAL provides up to two MIPI CSI-2 interfaces:
- Transfer of pixels and data received by up to two D-PHY receivers (CSI2_PHY1 and CSI2_PHY2) to:
- System memory, through 128-bit master interface on L3_MAIN interconnect
- VIP module, through a video port
- AM571x:
- CSI2_PHY1 with 4 data lanes / 1 clock lane
- CSI2_PHY2 with 2 data lanes / 1 clock lane
- AM570x:
- CSI2_PHY1 with 2 data lanes / 1 clock lane
- CSI2_PHY2 not supported
- Shared FIFO with 8 KiB size
- Maximum data rate of 1.5 Gbps per data lane
- Data merger for 2-, 3-, or 4-data lane configuration
- Error detection and correction
- Eight contexts to support eight dedicated configurations of virtual channel ID and data types
- On-the-fly differential pulse code modulation (DPCM) decompression
