CioRy Project Concept

Project Goal is “implement AUTOSAR BSW Stackinto All (100%) AUTOMOTIVE MCU”.

CioRy Project for Compact and Faster AUTOSAR BSW stack.

What is SunnyGiken?We have been building/making/creating Embedded system for 40 years!

Not to be able to implement AUTOSAR

BSW Stack to approximately

20～30% of MCUwhich are mainly Low-end MCU！

CioRy Project – There is a problem to have to be solved.

～ AUTOSAR BSW Stack are not to be able to implement toapproximately 30% of MCU which are mainly Low-end one! ～

AS Low-end MCU・・・ROM Size Factor

⇒ ROM Size is too large considering the slight quantities of functions they do.

Performance Factor⇒ Large overhead

influences Application processing.Introduction Factor

⇒ High AUTOSAR dependenceinfluences Development schedule.(Difficult to get off the ground)

CioRy Project can solve the problem!

～ Develop the BSW Stack technology which can implement to Small MCU! ～

Methods for solving problems!Let's develop the Compact and Faster AUTOSAR

BSW Stack which can implement to Low-end MCU!

～ Setting goals considering the needs of the Japanese market ～

Make it possible to implement AUTOSAR BSW Stack to Low-end MCU!

◆Make BSW Stack ROM Size smaller than 30KB!

Less than 30% with 128KB MCU.

◆CPU utilization of BSW Stack is less than 20%

at 32MHz operation frequency.

◆Easy introduction of AUTOSAR!

It is possible to implement AUTOSAR

on All (100%) AUTOMOTIVE MCU

if we can achieve these! Work Group is going to achieve

specifications requirements!

・Only CAN communication is enough.・Only LIN communication is enough.・GW function should be cope in SW-C.

⇒ All ECU do not need GW function.・Spec decision of Configurator is difficult・Needs Virtual-E2PROM(Memory Stack)

⇒ Rejected by high MCU dependence. ・Needs DIAG.

⇒ I/F only by high OEM dependence.・Demand for compact and quick response RTE.・AUTOSAR OS functions are enough with BCC1.・Simple software component.

- Summarize Demands.- Specifications adjustment.- Clarify uncertain points.- Improvement activity.- Consider MCU information.

Concept of Compact and Faster.

1）ICC1 adoption, and reduced module hierarchy by limiting the function toCAN/LIN communication.

2）Selected application and function, then implement only “Function to use”.3）Reduced handling of Signal Unit, because it has big overhead.

Will explain these from the following page.

Development approaches of Compact and Faster.

The frame is comprised of plural signals.

～ Technical consideration for accomplishment by Work Group: Directivity for the Compact and Faster BSW Stack! ～

★Inherits the high reusability standardization of AUTOSAR.⇒ SW-C modularization and Establishes MCAL reusability.

★AUTOSAR BSW Stack which pursued high efficiencywith compact by selected application and function.

⇒ ROM Size: less than 30KB, CPU utilization: less than 20%.

Inherits the high reusability standardization of AUTOSAR.

◆ Adapting AUTOSAR Specification to Upper I/F of RTE, and commonization of AUTOSAR specifications I/F SW-C is possible.

◆ The utilization of existing MCAL is possible by configuration able tointroduce AUTOSAR conformity MCAL easily.
