Xueyong Zhang, Arindam Basu

摘要:

在这项工作中,我们提出了一个混合存储器位单元并置SRAM和DRAM(CRAM)的存内计算(IMC)的基础上的图像复原(IR)和区域建议(RP)的11个晶体管组成。提出了一种鲁棒的RP更新算法来提高算法的性能。该工作证明了基于IMC的全局并行扩散和列/行投影,以实现最大能量效率为1220 TOPS/W的图像复原和915 TOPS/W时,结合区域建议。

英文摘要:

In this work, we present a hybrid memory bit cell - collocated SRAM and DRAM (CRAM) consisting of 11 transistors for in-memory computing (IMC) based image restoration (IR) and region proposal (RP). A robust RP updated algorithm is proposed to improve the performance. This work demonstrates IMC based global parallel diffusion and column/row-wise projection to achieve a maximal energy efficiency of 1220 TOPS/W for image restoration and 915 TOPS/W when combined with region proposal.
