JASPAR’s Approach to AUTOSAR Software
JASPAR Key Concept<br />
Achieve the best solution between “Performance” and “Reusability” of the<br />
AUTOSAR BSW<br />
Our approach:<br />
Reduce the number of API of AUTOSAR BSWs depending on the target system<br />
(Profiling)<br />
CAN Cluster<br />
ROM Usage<br />
Integrate each possible AUTOSAR BSWs and reduce the overhead of each<br />
functions (Clustering)<br />
Reduce of API<br />

Purpose of Profiling<br />
Performance Improvement of AUTOSAR BSW<br />
(性能向上)<br />
Achieve “resource reduction” and “performance improvement” by<br />
remove redundant specification (APIs)<br />
(冗長な仕様を削除することで「消費リソース削減」と「パフォーマンス向上」を実現する。)<br />
Workload Reduction of AUTOSAR BSW Configuration<br />
(コンフィグ作業の効率化)<br />
Reduce the workload of BSW configuration by providing template file<br />
for each profile<br />
(膨大なパラメータ設定作業をプロファイルに応じたテンプレートファイル提供で効<br />
率化する。)<br />
Reusability Improvement of AUTOSAR BSW<br />
(再利用の促進)<br />
Improve reusability by the optimized profile specification for real ECU<br />
(実ECUに最適化された仕様により再利用しやすくする。)<br />

AUTOSAR BSW uses large amount of ROM/RAM, and high load CPU because<br />
It is designed to fulfill all kinds of automotive electronics controllers.<br />
(AUTOSAR仕様は車載電子制御システムの各形態に対応できるように構成されているためマイコン<br />

JASPAR BSW <strong>Evaluation</strong>
<strong>Evaluation</strong> Approach<br />
JASPAR implemented the AUTOSAR software based on<br />
AUTOSAR specification release 3.0.<br />
In evaluation, “AUTOSAR Software” means JASPAR<br />
implemented AUTOSAR BSW based on Rel. 3.0 specification<br />
In evaluation, “JASPAR BSW” means JASPAR implemented<br />
AUTOSAR BSW with JASPAR concept.<br />

JASPAR Concept Summary<br />
1. Reduction of ROM and RAM usage<br />
By using Profiling, and Clustering concepts, regardless of the kind of<br />
application the reduction of ROM and RAM usage can be accomplished<br />
(プロファイル、クラスターコンセプト共、ROM、RAMのリソースについては、アプリケーションに<br />
関わらず削減できる。)<br />
2. Reduction of the CPU load<br />
The effect of the reduction of the CPU load using Profiling concept depends on<br />
the application<br />
The effect of the reduction of the CPU load using Clustering concept doesn't<br />
depend on the application (because Clustering concept is adapted to the<br />
communication stack, the application-common stack)<br />
(プロファイルコンセプトは、アプリケーションにより効果に差異が見られる。<br />
クラスターコンセプトは、処理負荷を軽減できている。しかし、通信部分に適用されており、アプリ<br />
ケーションの違いによる差異が少ないからと考えられる。)<br />
3. Difference in Software vendors<br />
The BSW performance differs between software vendors. It is because the<br />
difference in the understanding of a specification, and the implementation skills.<br />
( ソフトウェアベンダーによる差異は確実に見られる。これは、各ベンダーの仕様の理解度の違い、<br />
得意技術分野の差によるものと考えられる。)<br />
