Test System
[AVR / WinAVR]

The table below details the prototyping board and development tools with which the WinAVR (GCC) AVR tests were performed.

Hardware Setup

Prototyping board

STK500 prototyping board direct from Atmel



Clock Frequency

8Mhz stated but measured at 7.9MHz.

RAM interface

Internal to the processor

ROM interface

Internal to the processor

Development Tools Setup


GNU based WinAVR September 2003 build

Debug information

No debug information.


Various including: command line switch -Os (optimized for size), -O3 (full optimization) and -O0 (no optimization). The switch used is stated for each result.

It should be noted that although 8MHz is the maximum frequency for the AVR ATMega323, other processors in the family can be operated at 16MHz.
