Camera Subsystem unites three camera streaming
interfaces – receiver and transmitter, allowing the device to stream video inputs
from multiple cameras to the video processing accelerator (VPAC) or to internal
memory and to output CSI-2 protocol image data to any device that supports MIPI
CSI-2 protocol. Main modules are as follows:
- Camera Streaming Interface
Receiver (CSI_RX_IF) with the following main features:
- Compliant to MIPI
CSI-2 v1.3+ and MIPI CSI-2 v2.0
- Supports up to 16
virtual channels per input
- Supports one 4MP
camera or eight 2MP camera streams
- Supports data rate up
to 2.5 Gbps per lane (wire rate)
- Supports 1, 2, 3, or
4 Data Lane connections to MIPI D-PHY Receiver (DPHY_RX)
- Over 25 different
programmable formats including YUV420, YUV422, RGB, Raw, and User
Defined
- Supports four
independent (simultaneous) output streams:
- Two VP 32-bit
streams to VISS inputs of VPAC image processing
accelerator
- One (up to 4
channels) PPI 16-bit pixel retransmission interface to
Camera Streaming Interface Transmitter (CSI_TX_IF)
- One (up to 32
Channels) DMA interface through a 128-bit Packet Streaming
Interface Link (PSI_L) connection to NAVSS for transfers to
memory:
- Functional and data path
error interrupts
- ECC support
- MIPI D-PHY Receiver (DPHY_RX)
with the following main features:
- Allows the device to
input video streams from external sensor cameras and other CSI2
compliant sources
- Compliant to MIPI
D-PHY standard v1.2
- Supports up to 4 data
and 1 clock lanes
- Supports up to 2.5
Gbps (with deskew) and 1.5 Gbps (without deskew) per data lane
- Clock lane Control /
Interface logic type: CIL-SCNN for HS and low power receiving
- Data lane Control /
Interface logic type: CIL-SFAN for HS and low power receiving
- Data lanes can be
independently operated in HS or ULP mode
- Swapping of DP/DN
signals within each clock/data pair
- Camera Streaming Interface
Transmitter (CSI_TX_IF) with the following main features:
- Compliant to MIPI
CSI-2 v1.3+, MIPI CSI-2 v2.0, and MIPI D-PHY v1.2
- Data rate up to 2.5
Gbps per lane (wire rate)
- Supports 1, 2, 3, or
4 Data Lane connections to MIPI D-PHY Transmitter (DPHY_TX)
- Over 25 different
programmable formats including YUV420, YUV422, RGB, Raw, and User
Defined
- Support of 16 virtual
channels
- Support of four
configurable input streams
