Overview
Ethernet PHY is an IEEE 802.3u compliant single-port Ethernet physical layer transceiver, and low power consumption transceiver for 10BASE-Te, 100BASE-TX, operation. Through the Giga Media Independent Interface (GMII), the EPHY connects to the Media Access Control Layer (MAC), and on the media side, it provides a direct interface either to Un-shielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet or UTP5/UTP3 cable for 10BASE-Te Ethernet. The Ethernet PHY employ a low power and high-performance CMOS process. It contains the entire physical layer function of 100BASE-TX defined by IEEE802.3u, including the Physical Coding Sub- ayer (PCS), Physical Medium Attachment Layer(PMA), Twisted Pair Physical medium Dependent Sub-layer (TP-PMD, 100BASE-TX only). The EPHY also provide a robust auto-negotiation function, utilizing automatic media speed/duplex and protocol selection match. EPHY also support Auto MDI/MDIX function to simplify the network installation.

It is very important that the design aspects of the NB-IoT device protocol stack ensure low module cost and low energy consumption. This is required to match the industry expected module costs. This paper outlines some of the NB-IoT Protocol stack specification flexibilities and generic design aspects that are to be considered to meet the above requirements, especially with reference to LTE.
UniversalFlash Storage (UFS) was created for mobile applications and computer systems requiring high performance and low power consumption. These systems typically use embedded Flash based on the JEDEC standard eMMC. UFS was defined by JEDEC as the evolutionary replacement for eMMC offering significantly higher memory bandwidth. The standard builds on existing standards such as the SCSI command set, the MIPI Alliance M-PHY and UniPro as well as eMMC form factors to simplify adoption and development.
In this paper, we introduce a new high-level, dataflow programming language called C~ (“C flow”) that further increases productivity by raising the level of abstraction from behavioral descriptions, while overcoming the limitations of C for hardware design. We present the syntax and semantics of this language, and the framework that provides hardware and software code generation. This paper illustrates the benefits of using C~ for hardware design of a IEEE 802.3 MAC, synthesized for FPGA and for 90nm CMOS technology.

Since MIPI and MDDI standards both target interfaces to cameras and displays on mobile devices, are two separate standards really needed?
