超高速タイマーコンポーネント(サブミリ秒)
|
ＤＳＰで見つけたのは「TZTimer」コンポーネントでした。
以下 Readme からの抜粋。
----------
Similar to the vcl Ttimer component, but with a resolution of 0.1ms and accurate to 0.015ms.
(略)
Resolution could be improved considerably when the RDTSC (pentium) instruction is utilized, however I had to get this timer working on a 486 also.
It was tested on D2 and D3 for W95, it should also work on D1 and W3.1.
However it will not work in Windows NT (?).
Some observed timing measurements of Tztimer, compared with the (vcl) Ttimer
:
{ evaluation of 60 runs on W95, P133, D3}
interval (vcl) Ttimer Tztimer
100 ms 108 +/- 4 ms 99.3 +/- 0.14 ms
10 ms 59 +/- 5 ms 10.1 +/- 0.07 ms
1 ms 59 +/- 6 ms (!) 1.00 +/- 0.02 ms
0.1ms Not available 0.098+/- 0.015 ms
