1. 如何将 CoreMark 程序移植到 STM32 上
  
  标签：STM32 Coremark 程序移植 C语言 eembc
  
  CoreMark是一项测试处理器性能的基准测试。代码使用C语言写成，包含：列举，数学矩阵操作和状态及CRC等运算法则。目前CoreMark已迅速成为测量与比较处理器性能的业界标准基准测试。CoreMark的得分越高，意味着性能更高。在CoreMark的官网上可以大家可以看到各家处理器型号的CoreMark得分。也可以从CoreMark的官网上下载测试代码，亲自测一下自己手中的片子的性能。CoreMark官网的连接地址：http://www.eembc.org/coremark/index.php。本文将一步步来介绍如何将下载的CoreMark测试代码移植到STM32MCU上进行测试。

  标签：USB 3382 Data_Book
  
  USB 3382 Data_Book PCI Express Gen 2 to USB 3.0 SuperSpeed Peripheral Controller The USB 3382 is a PCI Express Gen 2 to USB 3.0 SuperSpeed Peripheral Controller. It features two PCI Express Gen 2 x1 ports and one USB 3.0 SuperSpeed client port. The USB 3382 provides a matching bandwidth at 5 GT/s between the PCI Express Gen 2 bus and the USB 3.0 SuperSpeed bus. The controller can easily add a USB 3.0 client port to an existing PCI Express system, as well as convert existing PCI Express functions (endpoints) to a USB 3.0 product. The internal high performance switch can configure the two PCI Express ports into one x1 upstream plus one x1 downstream, one x2 upstream, two x1 downstream, or one x2 downstream port. The flexibility allows different system configurations to achieve the maximum performance of the product. The USB 3382 provides two pairs of buffered, 100 MHz HCSL output clocks, for downstream ports (in adapter mode, one downstream port, and in root complex mode, one or two downstream ports), saving BOM cost by eliminating the need for extra clock buffer(s).
