本文提出一款功耗275mW的异构多媒体处理器，通过硅中介层（Si-interposer）堆叠集成，解决了增强现实等移动应用中对高外部存储带宽的需求。该处理器支持3D图形、视觉处理和浮点运算，并包含纹理缓存，克服了传统方案带宽不足、缺乏缓存等瓶颈。
processing, vision, and 3D graphics require high external memory bandwidth. In augmented-reality (AR) processors [1], both 3D graphics and vision operations are required, so memory bandwidth becomes even more critical. In [1], however, memory bandwidth is not considered, floating-point processing is not supported, and there is no cache memory for texturing, which is a performance bottleneck of common graphics pipelines. In this work, a heterogeneous multimedia processor is presented to process various mobile multimedia applications in a single chip on Si-interposer for high memory bandwidth. The implemented processor has 4 key features: (1) A transceiver pool (TRx) that reconfigures strength of output drivers according to the channel loss for IC-stacking on Siinterposer, (2) A mode-configurable vector processing unit (MCVPU) for framelevel parallelism, (3) An energy
