First USB 3.2 VIP and TestSuite: Enhances the Verification Solution for USB IP, SoC and Type-C Subsystems

USB has literally become universal and present in every device ranging from smart phones and personal computers, IoT and wearables, storage and networking, consumer electronics and gaming consoles, automotive and many other emerging verticals. The success of USB can be attributed to innovation with each new generation—the capability to transfer data as well as supply power for charging devices and ease-of-use with a variety of connectors and form factors.

PCIe 4.0: A Quick Primer on New Features

‘Big Data’, ‘IoT’, ‘Mobile’, ‘Networking’ and ‘Storage’ applications are the key drivers for next generation high-performance systems. To meet the bandwidth requirement of the emerging applications, it was required to either increase the lane width or speed. Increasing the lane width isn’t cost effective and thus increasing speed is the best viable option. PCIe 4.0 has doubled the per lane throughput to 16GT/s, compared to 8GT/s for PCIe 3.0, delivering higher performance without increasing the lane width.

SAS 24G: Beyond the 2x Speed

SAS (Serial Attached SCSI) continues to be the interface of choice for mission-critical storage sub-systems. SAS 24G is more than just a 2x speed-bump over previous generation of SAS 12GB, rather it’s a major overhaul of the technology.

Decoding SAS 24G: New Encoding and Features

SAS follows its own version of Moore’s law, doubling the speed every few years. Keeping up with the tradition, SAS 24G (Gen-5) was recently introduced. Let’s decode, how the effective speed has been doubled to 24G, though signaling rate remains at 22.5G. This has been achieved through a more efficient 128b/150b encoding scheme to realize a usable data rate of 24G while retaining compatibility with 6G and 12G. Additional features were also introduced to improve the overall protocol efficiency. Some of the newly added features include binary primitives, primitive parameters, SMP open priority, inter-expander fairness arbitration enhancements, … etc. In this blog we will look into some of the new features, and will continue to delve into more details in the upcoming blogs on SAS.
