The goal of the UniPro working group is to develop an open specification layered protocol. Main features and capabilities include high bandwidth, application agnostic, support for a network and forward compatibility to address market needs. Beginning with its first released specification in 2007, the group has continued to deliver specifications which anticipate the market demand.

Specifications are available to MIPI members only. For more information on joining MIPI, please go to Join MIPI.

Specification for Unified Protocol v1.6

Introduction

The Unified Protocol (UniPro) v1.6 specification defines a layered protocol for interconnecting devices and components within mobile device systems. It is applicable to a wide range of component types including application processors, co-processors and modems, as well as different types of data traffic including control messages, bulk data transfer and packetized streaming. Implementing the UniPro specification reduces time-to-market and design costs by simplifying the interconnection of peripherals. In addition, the extensible nature of the specification simplifies new feature implementation.

Target applications for UniPro include wireless handsets, tablets/netbooks, digital cameras and multimedia devices. UniPro is optimized for mobile applications and scalable from single link to full network. 

The document references the MIPI Alliance specification for M-PHY v3.0.

To aid in understanding the concepts presented in this specification, the UniPro description is loosely based on the ISO OSI Reference Model (OSI/RM).  
 

Scope

This document defines the protocol used to transfer data between Devices that implement the UniPro specification. This includes definitions of data structures, such as Packets and Frames, used to convey information across the Network. In addition, flow control, error handling, power and state management, and connection services are also within the scope of this document.

The PHY Adapter, Data Link, Network and Transport layer protocols are described in Section 5, Section 6, Section 7 and Section 8, respectively. The Device Management Entity (DME) is described in Section 9.

The electrical interface, physical layer timing and encoding, application-specific protocols and command sets are out of scope for this document.

The following figure shows the scope of this document as it relates to the OSI/RM.

Purpose

This specification can be used by manufacturers to design products that adhere to MIPI Alliance specifications for host processor and peripheral interfaces.

Implementing the UniPro specification reduces the time-to-market and design cost of mobile Devices by simplifying the interconnection of products from different manufacturers. In addition, implementing new features is simplified due to the extensible nature of the UniPro specification.
