• 中文摘要： 在本篇論文中，將RISC-style中有關記錄器檔案之運用管理方式，將可變window大小的情況，做一分析研究。吾人可尋找出一個最佳之方法，此最佳方式可視為固定window大小情況之一般化。同時，就實際應用上，吾人亦提出分析比較三種不同之方式，最後，以三種不同之benchmark程式，實驗比較之數據中，顯示其中一種one-step look aheadwith prediction之方式具有較優之效果，此等方法可以提供未來在RISC-style之VLSI處理機設計上一個重要之參考。
• 英文摘要： In this paper, a study and evaluation of register file management strategies for a variable window sizein a RISC-style machine are given and described. At first, an optimal strategy is proposed and given whichis theoretically upper bound of the register file management strategies. We will find that the optimal strate-gy described by Tamir is a special case of our optimal strategy. In other words, our optimal strategy is thegeneralized optimal strategy for register file management in the RISC-style machine. We also design threedifferent kinds of practical strategies for variable window size cases. Three benchmark programs are usedto evaluate their performance for procedure calls or interrupt handlings. Some experimental data are col-lected and studied. The results show that appropriate selection of a register file management strategy for avariable window size is attractive when compared with the strategy adopted in fixed window size.
