CodeVisionAVR Standard の特徴
|
- 32 bit 仕様, Windows
95, 98, NT 4.0, 2000, XP and Vista 32bit に対応
- 容易なIDE( Integrated
Development Environment ) 及び Cコンパイラ
-
オートインデント、キーワードハイライト機能付きエディタ
- サポートされるデータタイプ: bit,
char, int, short, long, float
|
|
- AVR仕様を拡張した機能:
- Accessing the
EEPROM & FLASH memory areas
- Bit level access to
registers
- Interrupt support
|
|
- コンパイラのコード最適化:
- Peephole optimizer
- Advanced variables
to register allocator, allows very efficient use of the AVR
architecture
- Common Block
Subroutine Packing, replaces repetitive code sequences with
calls to subroutines
- Loop optimization
- Branch optimization
- Subroutine call
optimization
- Cross-jumping
optimization
- Constant folding
- Store-copy
optimization
- Dead code removing
optimization
- Two memory models:
TINY (8 bit data pointers for chips with up to 256 bytes of
RAM) and SMALL (16 bit data pointers for chips with more than
256 bytes of RAM) for better code efficiency
- User selectable
optimization for Size or Speed
|
|
-
Cソースコード中に直接アセンブラコードを挿入可能
- RAMの効率的な使用:
キャラクタストリング定数はFLASHメモリにのみストア、他のAVRコンパイラのようにRAMへはコピーされない.
- Cソースレベルデバッグ, COFFシンボルファイル作成,
変数の観察、COFFファイルはAVR Studioへ読み込んで、CodeVisionで作成したCソースコードでのデバッグを可能にしています。
- Atmel’s In-Circuit
Emulatorsへの適合: ICE200, JTAG-ICE２, etc.
