Intel and ADI Announce Development of Heat Management Bus Technology
Intel Corp. and Analog Devices Inc. (ADI) announced a new bus technology that claims to improve and communicate heat dissipation and voltage management information in computer systems.
The two companies have co-developed and launched a new bus interface called the Simple Serial Transport (SST). The technology is said to enable faster and more precise communication of system efficiency, one of the determining factors in temperature and voltage within a variety of computing systems, according to ADI and Intel. By working in conjunction with a computer's core-logic chipset, the SST bus is claimed to reduce thermal management errors that can lead to a drop in computing performance, according to the companies.
The SST bus improves upon the existing 100-kilobits-per-second SMBus (System Management Bus) in high-performance computing applications by offering increased bandwidth and higher noise sensitivity. The SST bus relays key environmental information � such as temperature and voltage � directly to the system's core logic or dedicated ASIC fan-speed controllers, at a rate of 1-megabits-per-second.
When tested in the same environment on new PC motherboards, the SMBus measures about one error every 10,000 bits, compared to the SST bus' one error for every one billion bits processed, according to the companies.
