Definition: Mobile Industry Processor Interface (MIPI) is a family of interface standards developed by the MIPI Alliance. These standards define how components such as image sensors, cameras, and displays transfer high‑bandwidth data efficiently.
Key Characteristics of MIPI Interfaces
Although MIPI was originally created for smartphones and mobile devices, it is now widely used in industrial, automotive, and IoT systems that require compact, high‑performance connectivity.
Key characteristics of MIPI interfaces include:
- High‑speed data transfer for image and video streams
- Low power consumption
- Scalable architectures using one clock lane and multiple data lanes
What Is MIPI on an FPGA?
MIPI on an FPGA allows designers to seamlessly connect modern cameras, displays, and sensors to embedded and edge systems using flexible, low power programmable hardware. By combining high‑speed MIPI interfaces with FPGA programmability, designers can bridge, process, and route image and video data efficiently, without redesigning the host processor or system architecture.
This approach is widely used in embedded vision, industrial automation, medical imaging, robotics, and edge AI applications where adaptability, deterministic low latency, and power efficiency are critical.
When implemented on an FPGA, MIPI enables the device to act as an intelligent endpoint or bridge between MIPI devices and the rest of the system. Instead of relying solely on a processor with native MIPI support, designers can use an FPGA to adapt MIPI cameras or displays to many different interfaces.
An FPGA with MIPI capabilities can:
- Receive data from a MIPI CSI‑2 camera
- Transmit data to a MIPI DSI display
- Convert MIPI data to interfaces such as USB, PCIe, LVDS, or parallel video
- Perform real‑time image processing or aggregation
This flexibility allows system designers to integrate new sensors and displays without changing the main processor.
How Is MIPI Used on an FPGA?
FPGAs implement MIPI using hardened physical layers, such as MIPI D‑PHY, together with protocol and controller IP. Typical usage models include:
- FPGA as a MIPI Receiver - Captures video or sensor data from MIPI CSI‑2 cameras for processing or forwarding.
- FPGA as a MIPI Transmitter - Drives external displays using MIPI DSI.
- FPGA as a Protocol Bridge - Converts MIPI streams to USB, PCIe, or parallel interfaces so non‑MIPI processors can use modern sensors.
- FPGA as a Processing Engine - Performs scaling, color‑space conversion, sensor aggregation, or pre‑processing before data reaches the host.
Advantages of Using an FPGA for MIPI
Using an FPGA for MIPI connectivity provides several system‑level advantages:
- Design Flexibility – Supports a wide variety of cameras, displays, and interfaces
- Low Latency – Hardware‑based processing with deterministic timing
- Compact Solutions – Reduces external bridge and glue logic components
- Future‑Ready Designs – Easily updated through reprogramming
These benefits make FPGA‑based MIPI bridging ideal for systems that evolve over time or target multiple end markets.
Lattice MIPI FPGA Solutions
Lattice offers low power, small form-factor FPGAs optimized for MIPI camera and display applications. Any Lattice device can support MIPI D-PHY interfaces through a soft implementation, but Lattice's primary focus is on integrating hardened MIPI D-PHY blocks directly alongside programmable logic, which enables more efficient and compact designs.

Lattice CrossLink™-NX FPGA Family
The Lattice CrossLink-NX FPGA family builds on the original Lattice CrossLink platform by adding higher logic density, enhanced security, and modern architectural features.
Key capabilities include:
- Hardened multi‑lane MIPI CSI‑2 RX and DSI TX D‑PHY blocks
- Support for high‑resolution and multi‑camera configurations
- Instant‑on SRAM‑based architecture
These devices are ideal for sensor aggregation, format conversion, smart bridging, and embedded vision pre‑processing.
