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.

生成多项式的最高位必须是1。例如:CRC-CCITT标准的16位生成多项式:g(x)= x16+x12+x1+1;阶数r = 16 即:0x11021.最高位通常为1。

′问题描述: 设 X[0:n-1]和 Y[0:n-1]为 2 个数组,每个数组中含有 n 个已排好序的数。试设计一个 O(logn)时间的算法,找出X和Y的2n个数的中位数。 例如,当n=7,X=[1,3,6,7,8,9,10];Y=[2,4,5,11,12,13,14]时,X 和Y 的中位数是7。
