Explore the world of HyperBus memory devices in this 36-minute conference talk by Vignesh Raghavendra from Texas Instruments. Dive into the high-performance 8-bit Double Data Rate bus technology connecting SoCs with advanced flash devices. Learn about HyperFlash, a NOR-based, Common Flash Interface (CFI) compliant memory device replacing traditional parallel flashes. Discover the recently introduced HyperBus framework in the Linux kernel's Memory Technology Devices (MTD) subsystem. Gain insights into the HyperBus protocol, CFI specification, and kernel framework. Understand how to develop a new HyperBus Memory Controller Driver and explore improvements made to the CFI framework for supporting HyperFlash. Examine the challenges and unresolved issues in this field. The presentation covers various aspects, including HyperRAM, transaction phases, communication protocols, address space overlays, and comparisons with traditional SPI flash protocols.
