NVIDIA announced today the details of its new open standard for real-time monitoring and control of standard PC components.Called ESA (the acronym for Enthusiast System Architecture) the new standard is addressed to PC manufacturers and do-it-yourself enthusiasts who will be able to build finely-tuned and higher performance PCs. But what is ESA and how does it work? According to NVIDIA, ESA is based on USB specification. ESA defines new USB HID usages for monitoring and controlling ESA devices. This communication is enabled by embedding a microcontroller (containing a USB 2.0-compliant full speed device controller) into the ESA enabled component, and then connecting it through a USB cable to the PC Host. This cabling is typically accomplished internal to the PC chassis using a USB header on the motherboard, but an external USB connection is also supported. Once recognized by the host application, the ESA device can be monitored and controlled via the ESA protocol. |
