Power Management Support for i.MX6 WEC7 BSP from iWave Systems

Windows Embedded Compact 7 (WEC7) BSP by iWave Systems for Freescale’s SABRE SDP/B platform now supports power management.

Online PR News – 22-June-2013 – Bangalore – Windows Embedded Compact 7 (WEC7) BSP by iWave Systems for Freescale’s SABRE SDP/B platform now supports power management. Power management was successfully developed for the i.MX6 multicore platform and tested for the standard suspend and resume functionalities. During sleep the processor enters into dormant mode and consumes the least power. iWave has reduced the sleep mode power consumption with WEC7 BSP to very less level compare to Linux and Android BSPs. i.MX6Q has four CPU cores. The suspend power state not only turns off 3 CPU cores, but also puts the primary CPU on low power mode. On resuming, all 4 cores restart successfully.
WEC7’s Multicore support for Power Management Windows Embedded Compact 7 smartly integrates symmetric processor architecture into its existing kernel through its OEM Adaptation Layer (OAL). It provides standard OAL SMP functions to turn on/off multicores on a platform.

WEC7 Power management driver adheres to the MDD (Model Device Driver) and PDD (Platform Device Driver) layer for separation of the generic and platform dependant functionalities. OEM’s also do have the flexibility to customize the in-built power manager by cloning the library.

Features: Power Management on WEC7 SABRE SDP/B Platform supports following features: Dormant mode for ARM Cortex A9 multicore processor Power management of device drivers Customization of system power
State: User Idle, System Idle, Suspend and resume Applications: Power Management for multicore processors can be used in a wide variety of battery operated handheld devices like tablets, video cameras, mobile phones and other entertainment solutions.
