Higher Mobile Storage Performance at Lower System Cost

Higher storage performance at a lower cost can create a bottleneck in the design of storage devices.  In order to achieve higher performance, devices must use on chip DRAM, which adds to the overall cost. This is where Unified Memory Extension (UME), a JEDEC specification, comes into the picture. It is defined as extension to the JEDEC UFS (Universal Flash Storage) specification. JEDEC UFS device uses NAND flash technology for data storage. Unified Memory (UM) allows users to use part of the host memory as the device’s internal memory. Since the host memory is already available in large capacities, this mechanism provides a much bigger space for the device to use as a Write Buffer (WB) cache or to store information such as Logical to Physical (L2P) address translation tables. The UM area is physically located on the host side but ultimately belongs to the device, thereby replacing the device-integrated RAM, and reducing overall cost. Large space availability means the device can store larger amounts of WB of L2P table information resulting in higher storage performance.

MIPI CSI-2 v2.0: Emerging Applications in IoT, Drones and Automotive

MIPI Camera Serial Interface (CSI-2) is widely used as a camera interface in the mobile industry. MIPI Alliance is constantly working towards providing a solution to cater the increasing demand for higher-bandwidth and high-definition video like 1080p, 4K, and 8K. The MIPI Working Group released CSI-2 v2.0 to target emerging imaging and vision applications. It has extended the usages of CSI-2 to IoT, wearable devices, drones, Virtual Reality (VR) and Augmented Reality (AR), and automotive systems.

How to Address the Top 7 JEDEC-UFS Stack Verification Challenges Using Test Suites

If you are currently using or consider using JEDEC UFS protocol in your next design you might face several verification challenges.  The following blog will talk about 7 of the biggest challenges of UFS stack verification. With the fact that people are moving to reduced pin count and increased speed, an MPHY based stack has picked up momentum and provides an increased number of new applications to leverage the UFS stack. The UFS protocol is being adopted rapidly due to its higher performance, efficiency, concurrent multi-tasking, usage of the complete band width, security, and reliability and longer power life.

Energy Efficient Designs with MIPI

Getting the best out of available battery technologies continues to be a challenge for mobile design companies. When phones were used for voice only, the battery lasted a few days compared to less than a day in case of smartphones with high resolution screens, cameras, powerful processors, gigabytes of memories and running power hungry software. Consumers continuously demand more features and functions from their mobile electronics and with more functions converged into a single device, it’s becoming extremely challenging for SoC designs to keep up with the exploding bandwidth, advanced integration functionality and low power constraints.

MIPI UniPro Stack Based Design and Verification

Mobile phone market is very competitive and time to market is very critical for mobile system designs. It becomes important that the IP design and verification cycle is continuously optimized. MIPI UniPro is a layered protocol for interconnecting devices within a mobile system and allowing them to exchange information at high-data rates. JEDEC UFS and MIPI CSI-3 are the typical applications defined on top of UniPro stack. UniPro specification defines a set of standard signaling at application and physical layers that allows the development and verification of individual IP blocks in parallel. In this blog, I would describe various verification topologies possible in a UniPro design and stack based architecture of Synopsys UniPro VIP.
