  computational delay
In some cases, the ILP computational delay may become huge.
      
Two possible mapping techniques are discussed, which are (1) changing the dependence delay by introducing an additional companion pipeline; (2) changing the computational delay by inserting FIFOs.
      
In order to improve the computational delay, the size of the window is defined dynamically.
      
However, for high frequencies pulses propagating in a large domain, the computational delay is still penalizing, particularly for 2D and 3D computations.
      
In particular, both of these properties are strongly affected by the issue of computational delay.

In this paper, a practical formula for calculating the time lag of short wave being suited for a distance less than 1000 km is given. This formula derived directly is based on the virtual height of ionosphere. This virtual has been corrected by the periodic variations of sunspot for 11 years, and the annual and diurnal variations. It is as follows: τ=τ_0+τ_r+τ_s+τ_d(ms) τ_0=2.900 τ_r=0.0010R ±0.0007 τ_s=-0.048cos(2πt_s+28°.4) +0.014 +6°.6 τ_d=0.105cos(2πt_d-63°.7)-0.102cos(4πt_(d/2)+77°.0) ±0.039 ±9.6 ±0.039...

Finally, an example has been calculated. Using practical data of Wuchang Time Observatory of IGG and by means of the formulae of BIH and (7b), the compared results are given. The accuracy of results calculated by this formula is better than the accuracy calculated by BIH formula.

Nonlinear dynamic inversion is a simple and practical method for designing control laws for supermaneuver aircraft.But in application to practice,it is necessary to change the continous time control law into a discrete time form.Discretization of a multi variable nonlinear system is a complicated problem and there isn′t a a general way to solve it.This paper introduced a simple and direct implementation method for solving the problem. In the method,the control law basically remains the same form as that in the continous domain,and the control results obtained by using the highest sampling rate for ordinary fighters are very close to those in the continous domain.This paper also gave out a multi rate implementation of the discrete time control law to decrease the needs of computer capacity.The results of a multi rate control law are also very colse to those of the continous time system.Finally,som practical problems such as compute delay are discussed.

用非线性动态逆方法设计超机动飞机的控制律是一种简便可行的方法,但实际使用时需要解决控制律的离散化问题。多变量非线性系统的离散化是一个复杂的问题。本文根据逆方法和歼击机运动的特点,提出了一种简单直接的实现方法,该方法基本保留了连续域系统控制律的形式。用通常歼击机的最高采样频率来实现该方法,可以得到与连续域非常接近的控制结果。本文还提出了该形式的多速率实现方式,可以降低对机载计算机吞吐力的要求,其控制结果与连续域的差别仍很小。最后讨论了如计算时延等实际问题
