calltree - static call tree generator for C programs The calltree command parses a collection of input files (assuming C syntax) and builds a graph that represents the static call structure of these files. Calltree is similar to cflow(1) but unlike cflow(1), calltree is not based on lint(...
如下面左图所示,做一个矩阵乘,使用CPU计算需要三层for循环,而右图在昇腾AI处理器上使用vector计算单元,只需要两层for循环,最小计算代码能同时计算多个数据的乘加,更近一步,如果使用Cube计算单元,只需要一条语句就能完成一个矩阵乘的计算,这就是我们所说的SIMD(单指令多数据)。因此,我们通常使用AI处理器来进行大量...

Memset with Span.Fill:54ms Memset with for loop:74ms Memset with Array.Fill:3ms Span.Fill的效率相对Array.Fill差距还是有点巨大的,仅是比循环设定值快一些。 接下来看memcpy: //////内存拷贝测试;///[TestMethod]publicvoidMemcpyTest() {varbts =newbyte[1...

以下示例演示如何使用CryptEncodeObjectEx和CryptDecodeObjectEx。 可以轻松修改此示例以使用CryptEncodeObject和CryptDecodeObject。 此示例还使用修改后的函数版本ByteToStr打印抽象语法表示法一(ASN.1)编码的八进制数系列。 它还使用MyHandleError。 这些函数的代码包含在示例中。
