pixstats(1) — Commands
Digital
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 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.
RESTRICTIONS
pixstats models execution assuming a perfect memory system. Memory system events such as cache misses will increase execution above the pixstats predictions.
