In the short decade that I3C has existed, it has overhauled microchip communications. And with increased adoption of I3C around the world, debugging and validation have become more and more important for engineers. Although many I3C protocol analyzers and exercisers are available in the market, making the right choice can be confusing. If you are […]
Dynamic Address Assignment, or DAA, the process by which an I3C controller assigns unique addresses to every device on the bus, is one of I3C’s most powerful features. It’s also one of the most common points of failure during bring-up. DAA is highly timing-sensitive and dependent on both protocol correctness and electrical integrity. A single […]
Today, the accelerated (32 GT/s) PCIe Gen 5 speed and the vast throughput of AI clusters dominate the technical vernacular in the modern data center. But a revolution is going on “beyond the main bus. The communication layer that monitors the health of the hardware, manages power states and protects hardware security is moving from […]
The change to the more modern Universal Flash Storage (UFS) 4.1 marks a turning point in the data architecture of mobile and automotive systems. The protocol can deliver on-device generative AI and advanced ADAS sensor fusion with rates of up to 23.2 Gbps per lane, or High-Speed Gear 5 (HS-G5) Rate B. This speed increase, […]
The AI model is fine. The protocol stack down it is not. The flaw of It Works in the Lab. All of the on-device AI capabilities are verified during shipments. Face recognition gains straight off. The on-demand voice model is an immediate response. Real time camera processing is at full frame rate. The stories from […]
You have spent eighteen months on your new 5G flagship. Your RF department has adjusted your antennas to surgical accuracy. In laboratory, conditions controlled, the connection is an illusion. Yet there comes the truth, which is, the Carrier Certification. The hand-off fails. Band switching gives the throughput a precipitous fall. The connection is “live” though […]
You have just thrown away a small fortune in Gen 5 server chips. The datasheet promised 32 GT/s. Your promotional staff are already trumpeting about record throughput. But in the rack? The performance is tanking. The work loads in your multitennants are slacking, and your Express Lane is beginning to resemble rush hour at the […]
The amount of pressure to reduce the weight of wiring is extreme in the migration to Zonal Architectures and Software-Defined Vehicles (SDV). It has caused a significant architectural change that has concentrated high-speed Automotive Ethernet backbones as a form of consolidation in order to support both non-critical and infotainment data and safety-critical ADAS traffic. This […]
In the mobile industry, “Day 1” performance is easy to promote. But true engineering skill shows in “Day 180” performance. When a flagship device feels “laggy” after six months of real use, it’s rarely the processor’s fault. Usually, it’s a trade-off problem in the storage layer, especially how the system handles Single Level Cell (SLC) […]
xSPI vs OSPI Introduction In embedded systems and high-speed communication, xSPI (eXtended Serial Peripheral Interface) and OSPI (Octal Serial Peripheral Interface) are two popular protocols for interfacing with flash memory and other peripherals. While both are designed to improve data throughput over traditional SPI, they differ in architecture, speed, and implementation. Feature Comparison Feature xSPI […]
