NVMe storage-optimized PCIe interface gets an Interoperability Lab at University of New Hampshire
The drive to adopt NVMe (a storage-optimized variant of the PCIe interface standard for SSDs) led by the NVMe Work Group now has an interoperability lab at the University of New Hampshire. The UNH-IOL—a “neutral, third-party laboratory dedicated to testing … Continue reading
Want to avoid losing more than half of your SDRAM’s bandwidth? The right SDRAM controller configuration can help prevent the loss. Just ask Vivante.
Graphics processors (GPUs) suck bits out of SDRAMs the way vampires do what comes naturally to them in the immensely popular Twilight book series by Stephenie Meyer. In other words, GPUs need all the memory bandwidth they can get and … Continue reading
