According to various aspects, just-in-time system bandwidth changes may be implemented in hardware to optimize power consumption and performance in an electronic device. More particularly, in a periodic system associated with an electronic device, a bandwidth for a next frame may be configured during a current frame via software operating on the electronic device. Hardware associated with the periodic system may issue a bandwidth change request for the next frame when a current time reaches a bandwidth increase threshold in response to actual processing time associated with the current frame finishing prior to the bandwidth increase threshold, which may be defined relative to a timer deadline that defines when the next frame starts to process.

Methods, systems, and devices for processing display data are described. A device may receive a bitstream sequence including a quantity of intra-coded frames, inter-coded frames, or bi-directional frames, or a combination thereof. In some examples, the device may be a decoding device or an encoding device. Upon receiving the bitstream sequence, the device may determine a refresh pixel region for a frame based on an order of the quantity of intra-coded frames, inter-coded frames, or bi-directional frames, or a combination thereof. In some examples, the order may be an encoding order of the intra-coded frames, inter-coded frames, or bi-directional frames, or a combination thereof. The device may then send the refresh pixel region for the frame to a display device based on determining the refresh pixel region for the frame.
