The decoding algorithm used in RBDS.c is based on error trapping. The program emulates the operation of the encoder and decoder of a binary cyclic codes, using bitwise shifts and xor for modulo g(x) operations.

本書第二部分講述的是在Wi n 3 2平臺上的Wi n s o c k編程。對于眾多的基層網絡協議，
Wi n s o c k是訪問它們的首選接口。而且在每個Wi n 3 2平臺上，Wi n s o c k都以不同的形式存在著。
Wi n s o c k是網絡編程接口，而不是協議。它從U n i x平臺的B e r k e l e y（B S D）套接字方案借鑒了
許多東西，后者能訪問多種網絡協議。在Wi n 3 2環境中，Wi n s o c k接口最終成為一個真正的
“與協議無關”接口，尤其是在Winsock 2發布之后。
CCS編程環境 使用的是匯編加C的混合編程方法：
The programme of the Correlation Algorithm.
Using INT2 to get the input signal.
Array x, in first step, is the input signal produced by programme,
in next step, is the input signal get from A/D,
the length is 128, 32-bit floating point.
Array y, in first step, is the input signal produced by programme,
in next step, is the input signal get from A/D,
the length is 128, 32-bit floating point.
Array cor is the Correlation result, the length is 255, 32-bit floating point.
％DEFINEV Scaling vector and derivative

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It
permits you to download new code to the device over USB. This bootrom is
installed at address 0x00000000 in the ARM, which means that it is the
first piece of code to execute after reset. At startup, it waits for
a few seconds to see if the downloader is trying to connect. If not,
then the bootloader gives up control and jumps to your program. If the
downloader is trying to connect, then the bootloader receives the new
program over USB and writes it into flash.
