Overview
For Gigabit 10/100/1000 Ethernet applications, the GPHY is a highly integrated single chip. It is a singleport, IEEE 802.3u/ab compatible, power efficient Giga Ethernet physical layer transceiver. It can operate in 10BASE Te, 100BASE-TX, and 1000BASE-T modes. This GPHY uses either RGMII or GMII to connect to the Media Access Control Layer (MAC). It could support UTP5/UTP3 cable for 10BASE-Te Ethernet or Unshielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet and 1000BASE-T Giga Ethernet. It includes the Physical Coding Sublayer (PCS), Physical Medium Attachment Layer (PMA), and Twisted Pair Physical Medium Dependent Sub-layer (TP-PMD, 100BASE-TX only) as well as all of the physical layer functionality for 1000BASE-T as described by IEEE 802.3ab and 100BASE-TX, respectively. Additionally, this GPHY has a strong automated negotiation feature, automatic media speed- duplex selection, and protocol selection.

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?
