/*  該程序用于測試CH365的讀寫速度
  CH365的I/O和MEM讀寫速度是完全相同的,計算機程序是以字節,字(16位),雙字(32位)為單位讀寫,而實際上CH365總是將其轉換為字節讀寫,
  所以速度由以下幾個因素決定:
    CH365讀寫脈沖的寬度,可以是30nS到240nS,由CH365讀寫速度控制寄存器位3-位0決定,也就是CH365輸出RD和WR的低電平的寬度,
    CH365讀寫脈沖之間的間隔,也就是CH365輸出RD和WR的高電平的寬度,分為兩種:
         一種是兩次操作之間的間隔,也就是計算機程序發出的兩次讀寫操作之間的間隔,通常為300nS以上,與計算機本身硬件有關(最小能到240nS),
         另一種是單次操作之間的間隔,也就是CH365將字或雙字轉換為多個字節之間的間隔,可以是30nS或60nS,由CH365讀寫速度控制寄存器位4決定,
  1.最快的速度情形是:(設置CH365讀寫速度控制寄存器為0x00)
        讀寫脈沖寬度為30nS,單次操作之間的間隔為30nS,
        計算機程序以雙字(32位)為單位進行讀寫操作,實測速度可以達到7.5MB,理論值=4*1000/(300nS+30nS*4+30nS*3),乘4是因為雙字操作,
        在這種情形下外部電路的速度必須在25nS之內才能可靠工作,例如:25nS的高速雙口RAM,或者是CPLD/FPGA可編程器件
  2.較快的速度情形是:(設置CH365讀寫速度控制寄存器為0x12)
        讀寫脈沖寬度為60nS,單次操作之間的間隔為60nS,
        計算機程序以雙字(32位)為單位進行讀寫操作,實測速度可以達到5.3MB,理論值=4*1000/(300nS+60nS*4+60nS*3),乘4是因為雙字操作,
        在這種情形下外部電路的速度必須在55nS之內才能可靠工作,例如:35nS-55nS的雙口RAM,或者是CPLD/FPGA可編程器件,大多數TTL接口電路等
  3.最慢的速度情形是:(設置CH365讀寫速度控制寄存器為0x07)
        讀寫脈沖寬度為240nS,由于總是以字節為單位讀寫,所以單次操作之間的間隔沒有用到,可以設為30nS,
        計算機程序以字節(8位)為單位進行讀寫操作,實測速度可以達到1.7MB,理論值=1*1000/(300nS+240nS*1),字節操作,
        在這種情形下外部電路的速度可以在230nS之內,例如:各種RAM,各種ROM,各種FLASH,各種TTL接口電路,CH421,CMOS工藝8255A/8155A/8253A等
