完整教程下载地址: http://www.armbbs.cn/forum.php?mod=viewthread&tid=86980 第42章 STM32H7的DMA基础知识和HAL库API 本章节为大家讲解DMA1(Direct memory access controller,直接存储器访问控制器)和DMA2,相比前面章节的BDMA,功能要强些,属于通用型DMA。 42.1 初学者重要提示 42.2 DMA基础知识 42.3 DMA的HAL库用法 42.4 源文件stm32h7xx_hal_dma.c 42.5 总结 42.1 初学者重要提示 DMA1和DMA2均支持8路通道。虽然是8路,但这8路不是并行工作的,而是由DMA的仲裁器决定当前处理那一路。 DMA最大传输次数65535次,每次传输单位可以是字节、半字和字。 DMA的循环模式不可用于存储器到存储器模式。 DMA1和DMA2带的FIFO是4个32bit的空间,即16字节。 使用DMA的FIFO和突发需要注意的问题较多,详情可看本章2.7小节。 STM32H7的参数手册DMA章节对存储器到存储器,外设到存储器,外设到存储器模式的传输过程进行了讲解,推荐大家看完本章节后读一下。 42.2 DMA基础知识 DMA的几个关键知识点放在开头说: 由于总线矩阵的存在,各个主控的道路四通八达,从而可以让DMA和CPU同时开工

Regarding the bss segment and data segment in Unix

对着背影说爱祢 提交于 2020-01-10 10:53:09
问题 I read in my unix text book that bss is used to store the uninitialized variables(global declarations). This would mean that the static variables are stored separately and not in the bss. The only other place is the data segment. Here is my question: Is bss segment a part of the data segment or are they two entirely different set of memory segments? Also, why keep the global variables separately from the static variables? 回答1: The original idea is still there, although there are layers of

Python: memory usage statistics per object-types (or source code line)

僤鯓⒐⒋嵵緔 提交于 2020-01-10 10:09:44
问题 I am doing some heavy calculations with Python (using OpenCV and Numpy) and in the end, I end up with a lot of memory usage (>1GB) whereby all refs should be gone and I only have the end-result (which should not be more than a few MB). To debug this, it would be nice if I could get some stats somehow which show me how much object instances there are of what type, ordered by the total amount of memory they take (per object class). Or even nicer: Not per object class but per source code line

Profiling memory usage on App Engine

余生长醉 提交于 2020-01-10 10:09:06
问题 How can I profile memory (RAM) usage on my App Engine app? I'm trying to address errors related to exceeding the instance memory limit. I've tried these things and, so far, they don't work or don't provide what I need. Appstats. This doesn't provide memory usage details. Apptrace. It hasn't been updated since 2012 and depends on a deprecated version of the SDK. Doesn't work out of the box. Appengine-profiler. Doesn't provide memory stats.
