IPS/Watt 大概是这样的,可以看一下含光还是最高,但是Tenstorrent相对来说还是很好的。而且含光为了convolution我记得是有特殊的优化的,不单纯是systolic array。 对于啥时候能卖,文章里面说大概2021年。 个人感想 这个多核的架构在Tenstorrent这边说的很好,但是其实之前TPU的paper里面也讨论过了大核跟小核的架构优劣,不...
相比GPU,ASIC 一般可以根据负载特点设计脉动阵列(Systolic Array)架构,其根据负载的数据流特点设计计算器件的排布,让计算单元输入与输出流水线化,减少访存 脉动阵列的设计原则 其在单指令多数据流(SIMD)的基础之上,进一步降低访存,尽量在片上做更多的计算缓存中间结果,这样进一步提升芯片吞吐与降低延迟 将原来指令流水线...
其中一个代表就是谷歌 TPU(Tensor Processing Unit),通过对神经网络模型中的算子进行抽象,转换为矩阵乘法或非线性变换,根据专用负载特点进一步定制流水线化执行的脉动阵列(Systolic Array),进一步减少访存提升计算密度,提高了 AI 模型的执行性能。华为昇腾 NPU(Neural Processing Unit,神经网络处理器)针对矩阵运算专门优化...
tbl = readtable('patients.xls'); scatter3(tbl,'Systolic','Diastolic','Weight'); You can also plot multiple variables at the same time. For example, plot both blood pressure variables on the x-axis by specifying the xvar argument as the cell array {'Systolic','Diastolic'}. Then add ...
对于卷积层,PL端先对输入图像进行填充(如果需要),然后使用通用矩阵乘法GEMM(General Matrix Multiplication)原理,设计了一个基于systolic array的GEMM处理器。进行卷积运算,并使用查找表实现激活函数。对于池化层和上采样层,PL端使用简单的逻辑电路进行实现。对于YOLO层,PL端直接将输出结果写入DDR3。
scatter3(tbl,"Weight",["Systolic","Diastolic"],"Age") You can also use different indexing schemes for xvar, yvar, and zvar. For example, specify xvar as a variable name, yvar as an index number, and zvar as a logical vector. scatter3(tbl,"Height",6,[false false true]) ax— Axe...

根本上说,我们在机器学习加速器中可能做出的设计决策创建了一种更高级别的元搜索空间,因此,可以探索乘法的脉冲列阵(systolic array)在一维或二维情况下的大小,以及不同的缓存大小等等。 如前所述,考虑编译器优化与硬件设计的协同设计也很重要,因为如果默认编译器不会更改,就无法真正利用处理器中底层设计单元的变化。
