【简答题】
在某向量处理机上执行DAXPY的向量指令序列，即完成y=a×X+Y。其中X和Y是向量，最初保存在主存中，a是一个标量，已存放在寄存器F0中。它们的向量指令如下： LV V1，Rx ／／取向量X MULTFV V2，F0，V1 ／／向量X和标量(F0)相乘 LV V3，Ry ／／取向量y ADDV V4，V2，V3 ／／完成Y=a×X+Y SV V4，Ry ／／存结果 假设向量寄存器的长度MVL=64，Tloop=15，各功能部件的启动时间为： ①取数和存数部件为12个时钟周期。 ②乘法部件为7个时钟周期。 ③加法部件为6个时钟周期。 分别对于不采用向量链接技术和采用链接技术的两种情况，求完成上述向量操作的总执行时间。
