Ubiquitous Launches Fast-boot Technology
Tokyo-based Ubiquitous Corp. announced the availability of an ARM-focused technology claimed to load Android or Linux in one second. QuickBoot Release 1.0 preferentially restores memory areas necessary for booting from nonvolatile storage to RAM, says the company.
QuickBoot, which is available in a Linux SDK, is aimed at TVs, STBs, automotive infotainment systems, smartbooks, and smartphones, says Ubiquitous. QuickBoot 1.0 supports ARM9, ARM11, and Cortex-A series processors, says the company, which develops "compact, efficient and high-speed network and database software" for embedded devices.
The QuickBoot technology can boot up in about one second from complete power off, claims Ubiquitous.
It's said QuickBoot achieves its quick operation by preferentially restoring memory areas necessary for a restart from nonvolatile storage to RAM. QuickBoot restores necessary portions of the memory image by automatically determining the priority of memory usage for the system, says the company.
Restart time is not dependent on the amount of memory being used by the operating system, says Ubiquitous. This is because memory areas are read sequentially, and thus barely affect user operations, says the company.
The SDK also provides a QuickBoot BIOS and QuickBoot IRA (Intelligent Resource Allocator), enabling systems to start instantly by selecting necessary blocks of the stored memory image. All these components are provided as binary files, the company says.
Ubiquitous offers a kernel patch and boot loader sample as source code, as well as documentation. In addition, Atmark's Freescale i.MX31-based Armadillo-500 FX is provided as a reference board for ARM11-based devices.
Ubiquitous says it will continue to expand QuickBoot support for other CPU architectures, as well as for multi-core SMP devices using ARM Cortex-A series processors. The company also hopes to support additional operating systems, other than Linux or Android, although it does not say which ones. Ubiquitous is a member of the Solution Center for Android, and will provide QuickBoot to other SCAmembers upon request, says the company.
Kevin Smith, VP Segment Marketing, ARM stated, "Technologies such as QuickBoot enable greater energy savings, complementing ARM architectures that already provide industry leading energy efficiency levels."
