HDMI 2.1/2.0 bring significant improvements over previous versions in terms of speed, data integrity, and mode of data transmission. For more details on how HDMI has evolved, read our previous blog – HDMI 1.4 to 2.1: How it Became the Most Popular Display Interface.
DSC has enabled the use of high resolution displays in televisions, PC monitors, mobiles, and automotive infotainment systems. It provides a high quality, low latency algorithm to resolve the bottleneck of high bandwidth requirements needed to support the high resolution.
We recently published the VIP Newsletter for Q3 2018, containing trending topics, leading solutions, in depth technical articles, videos, webinars, and updates on next generation protocols. The newsletter covers content on DFI 5.0 for DDR5/LPDDR5, NVMe 1.3, USB 3.2, PCIe 5.0, next generation gaming displays, MIPI CSI-2 v2.1 for Automotive and IoT, and Verdi performance analyzer and protocol debug. In case you missed the latest buzz on Verification IP, you can read it here.
The growth of datacenter, storage, automotive and other emerging market applications is driving the development of next-generation memory technologies – DDR5, LPDDR5. Like their predecessors, the latest memory technologies also use DFI, a standard interface between memory controller and PHY, to reduce the integration cost and increase performance and data throughput efficiency. DFI also has evolved along with the memory technologies, and next generation DFI 5.0 is here to ensure higher performance in the systems using DDR5/LPDDR5. In this blog, we will discuss the new features of DFI 5.0 specification.
Debugging the complex serial protocols is the biggest challenge verification engineers face. It’s one of the most time and effort consuming activity affecting the schedule of every project. Traditional debug methodologies use a combination of loosely connected waveforms, log files, messages, and documentation, which are insufficient for productive debugging. Debugging SoC and block level issues using log files is tedious and time consuming. Design problems that appear in the later phases of the development cycle can be extremely difficult to track down and debug, thus putting project schedules at risk.
High speed memory interface is a critical component to support high speed data in applications like personal computers, mobile phones, and digital cameras. These applications require a high capacity and high performance NAND flash memory, and Toggle2NAND is one of the most suitable NAND interfaces.
With the arrival of HDMI 2.1 comes an array of remarkable features including the capability to support up to 10K resolutions at 120Hz. Such high resolutions are supported for a wider range of display applications such as externally connected displays (i.e. PC monitors and televisions), embedded display interfaces within mobile systems, and automotive infotainment systems. But with higher resolutions comes the requirement for higher bandwidth.
Higher performance at lower power is the most critical requirement of SoC designs, specifically those targeted towards mobile and consumer electronics applications. VESA (Video Electronics Standards Association), the technical standards organization for computer display standards, came up with a new power saving feature called PSR (Panel Self Refresh) in eDP 1.3. It is also available as an optional feature in DisplayPort. PSR helps to extend battery life in mobile phones, notebooks, and tablets, and is quickly being adopted in high-end designs.
Flash storage is one of the most important component of a smart phone, and with every new version comes higher memory capacity and performance. The most rapidly adopted flash memory technology in recent years is Universal Flash Storage (UFS), with UFS v2.1 providing a maximum data rate of ~11Gbps. JEDEC has come up with the faster next-generation UFS v3.0 which uses MIPI UniPro v1.8 (Unified Protocol) and MIPI M-PHY v4.1 as interconnect layer.
In mid-2014, the USB Type-C standard was announced, which provided a thinner, reversible connector and ever evolving ecosystem of new platforms like MHL, DisplayPort, HDMI, and Thunderbolt over Type-C. USB Type-C is quickly being integrated into most high end and newly-released mid-range smart phones offering the reversible Type-C connector. It is also becoming the connector of choice for IoT, display, gaming, and other emerging applications. Synopsys’ Subsystem Verification Solution for USB Type-C™ is rapidly being adopted by customers.
