基于verilog HDL的自動售貨機控制電路設(shè)計:
可以對5種不同種類的貨物進行自動售貨,價格分別為A=1.00,B=1.50,C=1.80,D=3.10,E=5.00 。售貨機可以接受1元,5角,1角三種硬幣(即有三種輸入信號IY,IWJ,IYJ),并且在一個3位7段LED(二位代表元,一位代表角)顯示以投入的總錢數(shù),最大9.90元,如果大于該數(shù)值,新投入的硬幣會退出,選擇貨物的輸入信號Ia,Ib,Ic,Id,Ie和一個放棄信號In,輸出指示信號為 Sa, Sb ,Sc ,Sd, Se 分別表示售出相應(yīng)的貨物,同時輸出的信號yuan, jiao代表找零,相應(yīng)每個脈沖代表找零相應(yīng)的硬幣,上述輸入和輸出信號均是一個固定寬度的脈沖信號。

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.
