Basic concepts covered include double-entry bookkeeping and examination of basic financial reports such as the balance sheet, statement of owner's equity and income statement.
Fast memcpy in c 1. Introduction This article describes a fast and portable memcpy implementation that can replace the standard library version of memcpy when higher performance is needed. This implementation has been used successfully in several project where performance needed a boost, including the iPod Linux port, the xHarbour Compiler, the pymat python-Matlab interface, the Inspire IRCd client, and various PSP games.
The story began when a co-worker of mine made an implementation of memcpy that he was very proud of. His implementation was faster than many standardized C library routines found in the embedded market.
When looking at his code, I found several places where improvements could be made. I made an implementation, which was quite a lot faster than my co-vorker's and this started a friendly competition to make the fastest portable C implementation of memcpy.
Both our implementations got better and better and looked more alike and finally we had an implementation that was very fast and that beats both the native library routines in Windows and Linux, especially when the memory to be copied is not aligned on a 32 bit boundary.
The following paragraphs contain descriptions to some of the techniques used in the final implementation. Mimic the CPU's Architecture One of the biggest advantages in the original implementation was that the C code was made to imitate the instruction sets on the target processor.
My co-work discovered that different processors had different instructions for handling memory pointers.SOLIDWORKS API: Easy Macros – Tree Display Keyboard Shortcut.
Let’s create an easy macro and assign a keyboard shortcut to it for quick access.
Create a New Macro. Let’s do the display state name for this example, and write this one from scratch, rather than recording it. It makes cleaner code. Microsoft Access date functions are a powerful way to retrieve and analyze data in your Access databases, but very few users know about these functions or how to use them.
