    • A method of performing cache coloring includes the steps of generating function strength information in response to a dynamic function flow representing a sequence in which a plurality of functions are called at a time of executing a program comprised of the plurality of functions, the function strength information including information about runtime relationships between any given one of a plurality of functions and all the other ones of the plurality of functions in terms of a way the plurality of functions are called, and allocating the plurality of functions to memory space in response to the function strength information such as to reduce instruction cache conflict.
    • 执行高速缓存着色的方法包括以下步骤:响应于表示在执行由多个功能组成的节目时调用多个功能的序列的动态功能流产生功能强度信息,功能强度信息 包括关于多个功能中的任何给定的一个功能与所述多个功能中的所有其他功能之间的运行时间关系的信息,并且响应于该功能将多个功能分配给存储器空间 强度信息如降低指令缓存冲突。

    • An ink jet printing head includes a plurality of pressure chambers having a natural period T2 for propagation of a wave, and a plurality of piezoelectric elements having a natural period T1 for oscillation. T1 and T2 are selected such that T1=n.multidot.T2 or T2=n.multidot.T1 wherein n is a natural number. The driving voltage for the piezoelectric elements has a rise time T3 selected at T3=m.multidot.T2 wherein m is a natural number not lower than two if T1=2.multidot.T2, or selected at T3=m.multidot.T2 wherein m is a natural number if T2=n.multidot.T1. The rise time T3 may be selected at T3=n.multidot.T1 in the latter case. Both the rise time T3 and the voltage level V of the driving voltage are selected in a single printing head so that V/T3 is a constant for attaining a gray scale level printing. The rise time T3 thus selected provides stable ink droplets without satellite ink droplets degrading the printing quality.
    • 喷墨打印头包括具有用于波的传播的固有周期T2的多个压力室和具有用于振荡的自然周期T1的多个压电元件。 选择T1和T2使得T1 = nxT2或T2 = nxT1其中n是自然数。 用于压电元件的驱动电压具有在T3 = m×T2选择的上升时间T3,其中如果T1 = 2xT2,其中m是不小于2的自然数,或者在T3 = m×T2处选择,其中如果T2 = n×T1,则m是自然数。 在后一种情况下,可以在T3 = nxT1选择上升时间T3。 在单个打印头中选择上升时间T3和驱动电压的电压电平V,使得V / T3是用于获得灰度级打印的常数。 如此选择的上升时间T3提供稳定的墨滴,而卫星墨滴降低了打印质量。
