Rapid display optimization based on on-chip programmable memory for mobile intelligent devices

Mobile intelligent devices are popular nowadays. As one type of embedded systems, such devices have strict response requirements. When the users click on the screen, the display should give the response as soon as possible. The on-chip programmable memory can be used to optimize the process. The main on-chip programmable memory is on-chip SRAM, which is called scratchpad memory. In this paper, a novel approach is proposed to speed the display for mobile intelligent devices based on scratchpad memory. The programs are analyzed and the most used parts are selected and assigned to on-chip programmable memory. Such memory has faster access speed and lower power consumption compared with the traditional off-chip memory and cache. The experimental results show that this approach has reduced the response time and improved the performance of the system.
