    • A method and apparatus for the manually optimizing the scheduling of code are disclosed. Accordingly, a software development tool with a graphical user interface enables manually ordering the scheduling of operations for architectures that execute multiple instructions/operations per machine cycle, such as very long instruction word (VLIW) processors. Assistance is provided at the instruction scheduling stage of VLIW compilation process to increase instruction level parallelism (ILP). The apparatus provides graphical views of assembly code and related information. An interactive, user friendly method to manipulate the code during or after scheduling is provided. The programmer can temporarily pause the automated scheduling, override decision taken by the scheduler, and then resume scheduling. The method lets the programmer interact graphically with scheduling decisions in a feedback environment. The method allows movement of only those operations that do not violate the target processor architectural constraints and algorithmic constraints of the code being optimized.
    • 公开了用于手动优化代码调度的方法和装置。 因此,具有图形用户界面的软件开发工具使得能够手动排序执行对于每个机器周期执行多个指令/操作(例如非常长的指令字(VLIW))处理器的架构的操作的调度。 在VLIW编译过程的指令调度阶段提供协助,以提高指令级并行性(ILP)。 该装置提供汇编代码和相关信息的图形视图。 提供了在调度期间或之后操纵代码的交互式,用户友好的方法。 程序员可以临时暂停自动调度,覆盖调度器所做的判定,然后恢复调度。 该方法允许程序员在反馈环境中与调度决策进行图形化交互。 该方法允许仅移动那些不违反目标处理器体系结构约束和被优化的代码的算法约束的那些操作。
