The arithmetic/ logic unit is the functional unit that provides the computer with logical and computational capabilities.

计算或逻辑单元：计算器是为计算机提供逻辑和计算能力的功能单元。

In the process of elliptic curve digital signature verification, the elliptic curve scalar multiplication and the elliptic point addition, which are under different coordinates, need to be calculated twice and once, respectively. With operands allocation, the two operations in the thesis are using the shared registers and arithmetic units as well as the same modular inverse process. No extra resource is needed for the introduction of point addition. Hence the resource utilization efficiency is optimized.

The workunits generated at first by the S5R4 workunit generator all at the upper end of the runtime variation for a given frequency band. They should average out over time, but at the beginning we got all "bad" ones.

S5R4目前的任务单元计算时间都偏长（译注：所以导致得分率的实际降低比例超过了25%），以后的任务单元计算时间平均来说会比较正常，但现在最早这批全是时间比较长的

Compared with common quadratic elements, this kind of interpolation method achieves the same accuracy by adding a rotation degree of freedom on every vertex without using midpoints of edges or interior points.

和一般的二次单元相比较，这种插值方法不需要使用单元边中点或者内部节点进行插值，仅在每个顶点上增加一个转角自由度就可以得到和二次元相当的精度；无论从运算时间还是数据所占用的空间来考虑，这类单元的计算花费均大大低于八节点四边形二次单元。
