NNIE的运行机制一：背景 由于当前主流算法中都使用了深度学习算法，而深度学习算法在移植过程中，基于带有的NNIE推理单元的Hisi芯片将极大的提高算法模型的推理，加速算法计算，从而便于算法落地上车。故而本文将简要说明NNIE的运行机制，主要包括如下部分：a:NNIE的运行机制b:单/双核NNIE的调度逻辑c:多算法并行的可能资源限制条件二: NNIE的运行机制 NNIE 是 Neural Network Inference Engine 的简称，是海思媒...

好久没刷题了, 搞起啊,不然脑袋要废了…https://leetcode-cn.com/problems/k-closest-points-to-origin/我们有一个由平面上的点组成的列表 points。需要从中找出 K 个距离原点 (0, 0) 最近的点。（这里，平面上两点之间的距离是欧几里德距离。）你可以按任何顺序返回答案。除了点坐标的顺序之外，答案确保是唯一的。示例 1：输入：points = [[1,3],[-2,2]], K = 1输出：[[-2,2]]解释：(1, 3) 和

最长回文字符串题目描述Catcher 是MCA国的情报员，他工作时发现敌国会用一些对称的密码进行通信，比如像这些ABBA，ABA，A，123321，但是他们有时会在开始或结束时加入一些无关的字符以防止别国破解。比如进行下列变化 ABBA->12ABBA,ABA->ABAKK,123321->51233214　。因为截获的串太长了，而且存在多种可能的情况（abaaab可看作是a...
