    • The present invention relates to a processing unit (1) for executing instructions in a computer system and to a method in such a processing unit. According to the present invention a decision is made whether or not to base execution on a value prediction (P), wherein the decision is based on information associated with the estimated time gain of execution based on a correct prediction. According to an embodiment of the present invention the decision regarding whether or not to execute speculatively is based on information (14) regarding whether a cache hit or a cache miss is detected in connection with a load instruction. In an alternative embodiment of the present invention the decision is based on information regarding the dependency depth of the load instruction, i.e. the number of instructions that are dependent on the load.
    • 本发明涉及一种用于在计算机系统中执行指令的处理单元(1)以及这种处理单元中的方法。 根据本发明,判定是否将执行值基于值预测(P),其中,所述判定基于与基于正确预测的估计的执行时间增益相关联的信息。 根据本发明的实施例,关于是否以推测方式执行的决定是基于关于是否与加载指令相关联地检测到高速缓存命中或高速缓存未命中的信息(14)。 在本发明的替代实施例中,该决定基于关于加载指令的依赖深度的信息,即依赖于负载的指令的数量。

    • A web-formed material (1), preferably a pulp web (1), is passed through a drying plant, comprising blow boxes arranged in a plurality of drying decks, floating above lower blow boxes, which at their upper sides blow out hot process air against the web-formed material (1). Water, in the form of steam, escaping from the web-formed material (1) is discharged by the process air, at least part of which is recirculated (43) whereas the non-recirculated process air is discharged as exhaust air (41) and is replaced by a corresponding portion of supply air (42) with a low water content. The temperature of the process air is controlled (4). If a deviation from the desired dry content of the dried web-formed material (1) is detected (6), the volume flow of the process air (40) is changed by increasing the volume flow of the process air (40) at too low a dry content in the web-formed material (1), and by decreasing the volume flow of the process air (40) at too high a dry content in the web-formed material, for the purpose of rapidly regaining the desired dry content of the dried web-formed material (1).
    • 网状材料(1),优选纸浆网(1),通过干燥设备,其包括布置在多个干燥甲板上的吹气箱,浮动在下吹风箱上方,在其上侧吹出热过程 空气抵靠网状材料(1)。 从网状材料(1)排出的蒸汽形式的水由处理空气排出,其中至少一部分再循环(43),而不再循环的处理空气作为废气(41)排出, 并且被具有低含水量的供应空气(42)的相应部分代替。 控制工艺空气的温度(4)。 如果检测到与干燥的幅材形成材料(1)的所需干含量的偏差(6),则处理空气(40)的体积流量也通过增加处理空气(40)的体积流量而改变 在网状材料(1)中的干燥含量低,并且通过在幅材形成的材料中以过高的干燥含量减小处理空气(40)的体积流量,以迅速恢复所需的干燥含量 的干燥的网状材料(1)。
