UniPro stands for Unified Protocol and is a Mobile Industry Processor Interface (MIPI) Alliance standard.
It defines a layered protocol on a high-speed serial interface for interconnecting devices
and components within mobile systems such as cellular telephones, handheld computers,
digital cameras, and multimedia devices. UniPro features data exchange at high data rates with
low pin counts and at low energy per transferred bit.
A suite of general-purpose features aims to make UniPro applicable for a wide range of
component types (e.g. application processors, coprocessors, modems, peripherals)
and different types of data traffic (e.g., control messages, bulk data transfer, packetized streaming).

| Use Cases |
 |
| Feature Overview |
UniPro provides reliable data transmission based on CRC and autonomous
packet retransmission in case of errors, as well as credit-based flow control.
Support of up to 2048 configurable CPorts, each of them representing a connection
to an application at one of the 128 addressable peer devices, and up to 2 traffic
classes with different priorities.
|
| MIPI D-PHY Interface |
Current versions of UniPro are specified to have an Extended PHY Protocol Interface (EPPI)
with 8b9b line coding for connecting a MIPI D-PHY. Each lane of such a physical layer
supports up to 800 Mbps. As UniPro allows data exchange via up to 4 lanes in each direction,
the resulting maximum data rate is 3.2 Gbps. Furthermore, in addition to the high performance
mode, also a low speed power-saving mode is supported.
|
| Reduced Time-to-Market and Design Costs |
Due to the simplified interconnection of products from different manufacturers. |
