Various aspects include methods for managing memory subsystems on a computing device. Various aspect methods may include determining a period of time to force a memory subsystem on the computing device into a low power mode, inhibiting memory access requests to the memory subsystem during the determined period of time, forcing the memory subsystem into the low power mode for the determined period of time, and executing the memory access requests to the memory subsystem inhibited during the determined period of time in response to expiration of the determined period of time.

Forced idling of memory subsystems

Methods and apparatus to manage image signal processor (ISP) data traffic is provided. The apparatus includes an ISP having an ISP front-end configured to receive image data and a first memory configured to store the image data. The ISP front-end is further configured to output the image data stored in the first memory to a second memory via a memory link in response to the image data stored in the first memory reaching a size threshold. Another apparatus includes apparatus includes a camera sensor configured to output image data in a camera mode, an ISP on a die, a camera link coupling the camera sensor and the ISP, a memory, and a memory link coupling the ISP and the memory. The memory link is configured to enter a low-power mode in the camera mode.

Image signal processor data traffic management

An image capture device that includes an adjustment circuit configured to monitor image parameters, generate updated image settings for the image capture device in response to the monitored image parameters, and transmit the updated image settings to one or more processors. The updated image settings configure the one or more processors to determine whether to transition the image capture device from a dynamic scene mode to a static scene mode based on a first image parameter included in the monitored image parameters, wherein the first image parameter is different from a second image parameter used to determine to transition the image capture device from the static scene mode to the dynamic scene mode, and to suspend generation of all or less than all of the updated image settings in response to determining to transition the image capture device from the dynamic scene mode to the static scene mode.

Power saving techniques for an image capture device

The disclosure describes a method for performing a fixed point calculation of a floating point operation (A // B) in a coding device, wherein A // B represents integer division of A divided by B rounded to a nearest integer. The method may comprise selecting an entry from a lookup table (LUT) having entries generated as an inverse function of an index B, wherein B defines a range of values that includes every DC scalar value and every quantization parameter associated with a coding standard, and calculating A // B for coding according to the coding standard based on values A, Band B, wherein Band Bcomprise high and low portions of the selected entry of the LUT. The techniques may simplify digital signal processor (DSP) implementations of video coders, and are specifically useful for MPEG-4 coders and possibly others.
