CIC 补偿滤波器。采用两种方法来设计，一个是frequency sampling method。另一个是Equal Rippler Design Method。这是一个非常有用的matlab代码。(CIC compensation filter. Two ways to design a frequency sampling method. The other is an Equal Rippler Design Method. This is a very useful matlab code.)

PicoRV32 is a CPU core that implements the RISC-V RV32IMC Instruction Set. It can be configured as RV32E, RV32I, RV32IC, RV32IM, or RV32IMC core, and optionally contains a built-in interrupt controller. Tools (gcc, binutils, etc..) can be obtained via the RISC-V Website. The examples bundled with PicoRV32 expect various RV32 toolchains to be installed in /opt/riscv32i[m][c]. See the build instructions below for details.

自己做的数码管显示的时钟 一个非常简单的FPGA时钟 用累加做的(To do their own digital display clock of the FPGA clock is a very simple to do with the cumulative)

主控cc2530通过debug接口对目标cc2530进行程序烧写，使用DMA进行数据传输，已调试通过。(Master cc2530 through the debug interface for writing the program to target cc2530, using the DMA data transfer, has been work successful.)
