RISC状态机由三个功能单元构成:处理器、控制器和存储器。
RISC状态机经优化可实现高效的流水线操作。
RISC 中的数据线为16位。
在数据存储器中的0到15的位置放置16个随机数,求16个数的和,放在数据存储器的16、17的位置,高位在前
对这16个数进行排序,从大到小放置在18到33的位置
求出前16个数的平均数,放在34的位置
基本指令有NOP, ADD, SUB, AND, RD, WR, BR,BC。
因为采用16位指令,有扩充的余地。-RISC

语言:VHDL
功能:该PN4序列的特点为将一个4位序列的前两位取异或,再让序列左移一位,用异或的结果作为序列的最后一位。序列周期是15,即15位伪随机序列。其中包括序列的产生模块和检测模块。对于误码检测,首先捕获相位。然后,规定测试的码的总个数,统计这些码中有多少个不能满足PN序列特点的,用计数器统计个数。如果发现误码过多,可能是相位失调,重新捕获相位,再进行误码检测。
