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.
