Abstract:
1. An apparatus comprising: a signal splitter to split a video image into a first data portion and a second data portion based on type of data or activity of data within the video image, wherein the first data portion includes more active data than the second data portion; a display frame buffer including a first memory component having a first type of memory and a second memory component having a second type of memory, the signal splitter to write the first data portion from the splitting of the video image to the first memory component and the second data portion from the splitting of the video image to the second memory component, wherein the first type of memory has a first power characteristic for power consumed in read and write accesses and the second type of memory has a second power characteristic for power consumed in read and write accesses, the first power characteristic being a symmetric power characteristic for read and write accesses and the second power characteristic being an asymmetric power characteristic for read and write accesses; and a signal combiner to read the first data portion from the first memory component and the second data component from the second memory component, and to combine the first data portion and the second data portion to generate a combined video image.
