CSR Synergy™

CSR Synergy™ は、さまざまなワイヤレス接続技術を最適化するために、総合的なホスト ソフトウェア ソリューションを提供します。

CSR Synergy により、一般的な統合や相互運用性の問題なしに機能群を追加することができます。CSR Synergy は、成功を収めた BCHS をベースとしています。BCHS は現在世界で最も一般的に使用されている組み込み Bluetooth® ソフトウェア スタックです。BCHS® と同様、CSR Synergy は ANSI C のソースコードを備え、簡単に拡張でき、 持ち運びが簡単な仮想 OS を搭載しています。CSR Synergy を使用することで、OEM 企業が移植すべきソリューションはわずかひとつになるので、個別のソリューションよりも、移植ジョブに必要なメモリフットプリントやリソースは少なくて済みます。また、CSR Synergy から技術を削除したり、CSR Synergy に技術を追加するのも簡単です。
