NAME

pixstats − analyze program execution

SYNOPSIS

pixstats program [ options ]

DESCRIPTION

pixstats analyzes a program’s execution characteristics.  To use pixstats, first use pixie(1) to translate and instrument the executable object module for the program.  Next, execute the translation on an appropriate input.  This produces a .Counts file.  Finally, use pixstats to generate a detailed report on opcode frequencies, interlocks, a mini-profile, and more. 

OPTIONS

−cycle ns Assume a ns cycle time when converting cycle counts to seconds. 

−r2010 Use R2010 floating point chip operation times and overlap rules.  This is the default. 

−r2360 Use R2360 floating point board operation times and overlap rules. 

−disassemble Disassemble and show the analyzed object code.

BUGS

pixstats models execution assuming a perfect memory system.  Cache misses etc. will increase execution above the pixstats predictions.
