 TPHRT 3.0 - TP 5.5 High Resolution Timer Toolkit   Ryle Design 23.07.1990

Таймер высокого разрешения для TP5.5 и DOS. Позволяет производить измерения с точностью до микросекунд за счет перепрограммирования системного таймера и подмены прерываний Int08h, Int1Ch. Приведены только примеры и TPU модули, без исходника.
TPHRT (Turbo Pascal High Resolution Timer) is a software library that provides the software developer with reliable timing functions that work across the entire Intel 80xxx PC compatible hardware environment with microsecond resolution. The TPHRT timing logic calibrates itself to the host PC clock rate and processor environment at run-time, so a single executable program will yield accurate results regardless of the host microprocessor and clock speed. Included: Samles, Docs and TPU5/5.5 only :(

TPHRT Turbo Pascal High Resolution Timer Toolbox Version 3.00 Shareware Evaluation Version Ryle Design P.O. Box 22 Mt. Pleasant, Michigan 48804 (517) 773-0587 Cserv 73047,1765 Introduction TPHRT (Turbo Pascal High Resolution Timer) is a software library that provides the software developer with reliable timing functions that work across the entire Intel 80xxx PC compatible hardware environment with microsecond resolution. The TPHRT timing logic calibrates itself to the host PC clock rate and processor environment at run-time, so a single executable program will yield accurate results regardless of the host microprocessor and clock speed. TPHRT is the definitive choice for any PC application that requires precision timing. Some typical TPHRT applications are: Source Code Timer/Profiler By adding timer calls to source code under development, TPHRT can generate a detailed summary of execution time by program subroutine and immediately illustrate the software's "hot spots" that might benefit from further code or algorithm optimization. Unlike "binning" profilers that display the number of "hits" in a range of program addresses, TPHRT provides a direct one to one correspondence between source code and elapsed time with user defined granularity. Hardware Performance Evaluator The high resolution and self calibration features of TPHRT make it ideal for insertion in code to evaluate hardware performance. Disk drives, numeric processors and CRT controllers can all have their throughput measured very accurately with TPHRT, and with numerous timers at the users disposal, many device functions may be independently measured in a single run. The formatted timer report generated by TPHRT makes compilation and interpretation of test results painless. Process Control With TPHRT, process control applications that require precise timings or precision delays are easy to implement. No longer will the application developer have to make an educated guess as to how long a critical interrupt is taking to service an I/O port as TPHRT can time virtually any hardware or software interrupt and provide the developer with precise accurate timings of the critical procedure. The precision delay functions allow the programmer to implement data acquisition loops with microsecond resolution. Timing and Scoring TPHRT is the perfect "timer engine" to build a timing and scoring system for use in nearly any competitive event. With its microsecond resolution and self calibration features, TPHRT surpasses conventional sports timing equipment resolution and allows the application developer to package high resolution timing and complete scoring functionality in a single package.
