PIXSTATS(1)         RISC/os Reference Manual          PIXSTATS(1)



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.

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

     -r2010
          Use R2010 floating point chip operation times and over-
          lap 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.
