摘要：
The vehicle head-up display (HUD) system displays the source image plane on the windshield surface by image warping. Non-linear access to source image pixels degrades memory access efficiency. To solve this problem, a Cache is designed to ensure pixel access continuity, reduce memory access numbers and improve bandwidth resource utilization. To optimize the performance of Cache, a storage separation management technology and an address multi-level comparison technology are proposed to improve the storage density of image pixels and save logical resources. In addition, a method for dynamically adjusting the Cache capacity is proposed to reduce storage resource usage and power consumption while ensuring the hit rate. The experimental results show that the storage separation management technology saves storage resources by 25%. The address multi-level comparison technology saves logical resources by nearly 10%. The Cache capacity can be reduced by the dynamic adjusting method by 75%, dynamic power consumption is reduced by 67.578%, and static power consumption is reduced by 14.060%. © 2020, Editorial Board of JBUAA.
