The Computer Hardware Understanding Developer Tools (CHUD Tools) are designed to help hardware and software developers measure and optimize the performance of PowerPC Macintosh systems running their products under Mac OS X.

Apple CHUD Tools is a tool that supports the latest in Macintosh hardware (G5) and software (Mac OS X 10.3, Panther).

Here are some key features of "Apple CHUD Tools":

· Shark - source line level profiling tool which shows you where time is being spent (both user and supervisor code), and correlates performance events to your program's code
· MONster - provides direct access to performance counters and presents the data in both spreadsheet and chart form
· Reggie SE - allows you to view the contents of PowerPC special purpose registers as well as PCI configuration registers
· Saturn - exact, function-level profiler with which you can generate and view a complete function call trace of your application
· BigTop - graphing front-end to top and vm_stat useful for monitoring system performance
· PMC Index - search tool for finding performance counter events and their setup
· CacheBasher - measures memory hierarchy performance under a wide range of conditions
· Skidmarks GT - processor benchmark which measures integer, floating-point and vector performance
· Spindown HD - monitors the power state of drives connected to the system
· CPU.pref - enable/disable second processor on dual processor machine on the fly
· acid - analyzes instruction traces and presents detailed analysis and histogram reports
· amber - captures the instruction and data address stream generated by a processes running in MacOS X, and saves it to disk in TT6, TT6E or FULL format.
· chudRemoteCtrl - command line tool for remotely starting MONster or Shark.
· monster - scriptable command line version of MONster
· shark - scriptable command line version of Shark
· simg4 - PPC7400 simulator
· CHUD.framework - programmatic access to many of the features of the CHUD tools.

Requirements:

· Developer Transition Kit (DTK) systems are no longer supported.
