Sage Electronic Engineering, www.se-eng.com, has established a new benchmark in fast boot, with a sub-second boot to a Real-Time Operating System (RTOS) for the XPedite7450 board manufactured by Extreme Engineering Solutions, Inc. www.xes-inc.com.
“We have fully realized instant-on capability, which did not exist before today in a high-reliability environment,” said Sage CEO Scott Hoot. “A SageBIOS™ BSP is booting a fully embedded VxWorks operating system from power on to full OS load in less than a second.”
A principal element of the SageBIOS Board Support Package solution was fully configuring four gigabytes of ECC (Error Correcting Code) DIMMs that protect against internal data corruption, said Marshall Dawson, senior member of the Sage Technical Staff. Normally the ECC DIMM configuration (setting all values to zero) would require about 160 milliseconds per GB, but Dawson wrote an algorithm that cut that configuration time by more than half.
"Sage and X-ES worked together to bring fast boot capability to multiple X-ES products, including XPedite7450,” said Matt Starzewski, principle embedded engineer at X-ES. “Coreboot® and the Intel® Firmware Support Package (Intel® FSP) offer a minimalist firmware framework that lends itself well to boot time optimization.”
