设计一个可编程间隔定时器，完成8253的功能，实现以下几点要求：
1、 含有3个独立的16位计数器，能够进行3个16位的独立计数。
2、 每一种计数器具有六种工作模式。
3、 能进行二进制/十进制减法计数。
4、 可作定时器或计数器。
-The design of a programmable interval timer, 8253 to complete the function, realize the following requirements: 1, contains three independent 16-bit counter, capable of three independent 16-bit count. 2, each with six counter mode. 3, can be binary/decimal subtraction count. 4, can be used for the timer or counter.

fpga_security
The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic
aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.

STM32F407FFT
使用STM32官方提供的DSP库进行FFT，虽然在使用上有些不灵活（因为它是基4的FFT，所以FFT的点数必须是4^n），但其执行效率确实非常高效，看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)
