NAME

pixstats − analyze program execution

SYNTAX

pixstats program [ options ]

DESCRIPTION

The pixstats command analyzes a program’s execution characteristics.  To use pixstats , invoke the pixie() command to translate and instrument the executable object module for the program.  Then execute the translation on an appropriate input.  This produces a .Counts file.  You can then 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. 

−disassemble Disassemble and show the analyzed object code. 

RESTRICTIONS

The pixstats command models execution assuming a perfect memory system.  Cache misses, and so on, increase execution above the pixstats predictions.
