    • A superscalar processor and method for executing fixed-point instructions within a superscalar processor are disclosed. The superscalar processor has a memory and multiple execution units, including a fixed point execution unit (FXU) and a non-fixed point execution unit (non-FXU). According to the present invention, a set of instructions to be executed are fetched from among a number of instructions stored within memory. A determination is then made if n instructions, the maximum number possible, can be dispatched to the multiple execution units during a first processor cycle if fixed point arithmetic and logical instructions are dispatched only to the FXU. If so, n instructions are dispatched to the multiple execution units for execution. In response to a determination that n instructions cannot be dispatched during the first processor cycle, a determination is made whether a fixed point instruction is available to be dispatched and whether dispatching the fixed point instruction to the non-FXU for execution will result in greater efficiency. In response to a determination that a fixed point instruction is not available to be dispatched or that dispatching the fixed point instruction to the non-FXU will not result in greater efficiency, dispatch of the fixed point instruction is delayed until a second processor cycle. However, in response to a determination that dispatching the fixed point instruction to the non-FXU will result in greater efficiency, the fixed point instruction is dispatched to the non-FXU and executed, thereby improving execution unit utilization.
    • 公开了一种用于在超标量处理器内执行定点指令的超标量处理器和方法。 超标量处理器具有存储器和多个执行单元,包括固定点执行单元(FXU)和非固定点执行单元(非FXU)。 根据本发明,从存储在存储器中的多个指令中取出要执行的一组指令。 然后如果将固定点算术和逻辑指令仅发送到FXU,则可以在第一处理器周期期间将n个指令(尽可能最大数)分派到多个执行单元进行确定。 如果是这样,n个指令被分派到多个执行单元执行。 响应于在第一处理器周期期间不能调度n个指令的确定,确定是否可以调度固定点指令,以及是否向非FXU分派定点指令以执行将导致更高的效率 。 响应于确定不能发送固定点指令或者将定点指令分派到非FXU不会导致更高的效率,所以定点指令的调度被延迟到第二处理器周期。 然而,响应于将定点指令发送到非FXU的确定将导致更高的效率,将定点指令分派到非FXU并执行,从而提高执行单元的利用率。

    • Disclosed is a thermoplastic felt structure for an automobile interior substrate, comprising a pair of mat units, each mat unit having a felt layer which is made by a mixture of a jute fiber and a PP fiber mixed in the weight ratio of about 5 to 5˜6 to 4 and a PP foaming fiber adhered to one side of the felt layer, said mat units being coupled each other on the other sides of the felt layers. With this configuration, a thermoplastic felt structure for an automobile interior substrate can prevent a deflection thereof, and have high strength and stiffness, heat-resistance and impact-resistance. Further, the present thermoplastic felt structure can decrease the cost of raw material, enhance the fuel efficiency with a lightweight body, and accomplish a simple manufacturing process.
