The DHRY program performs the dhrystone benchmarks on the 8051.
Dhrystone is a general-performance benchmark test originally
developed by Reinhold Weicker in 1984. This benchmark is
used to measure and compare the performance of different
computers or, in this case, the efficiency of the code
generated for the same computer by different compilers.
The test reports general performance in dhrystones per second.
Like most benchmark programs, dhrystone consists of standard
code and concentrates on string handling. It uses no
floating-point operations. It is heavily influenced by
hardware and software design, compiler and linker options,
code optimizing, cache memory, wait states, and integer
data types.
The DHRY program is available in different targets:
Simulator: Large Model: DHRY example in LARGE model
for Simulation
Philips 80C51MX: DHRY example in LARGE model
for the Philips 80C51MC
Please read this document before attempting to compile and run the libraries and applications! The projects
must be compiled in a particular order. Standard support questions are about compiler and/or linker errors
that are generated when users try to compile the projects in the wrong order. Other information of interest
is available here, so read the entire document fi rst.
Wild Magic Version 2.1 is what ships with the fi rst printing of the Game Physics book. Some of the
applications that are referenced in the book did not make it onto the CD–ROM for the book. Version 2.2
contains those applications, plus more

if the method is to be made void, then it cannot have a return statement, all it can do is set the value. Your SeatReserved variable is already a global variable, so what you have in the last post will work, it is known as a set or setter method. All it does is set a value, usually these are done accross classes.
I ll probably write up a short article next week outlining how the ActionScript works, so people can modify it, and work with it more easily in Flex.
You can download the component and source code here. There are some instructions in the FLA on how to use it. Note that this is not a compiled component, so it won t show up in the components panel. You will have to copy the component, and the source file into your project. If anyone really wants a compiled version, let me know and I can provide one.
As always, I d love to hear how people use it, and would appreciate it if you would post back to the comments if you make any significant modifications so that other people can benefit from them.
