[introduction]Functional securityA crucial design that is car system thinks, to apply the brake, change direction and advanced drive support system (ADAS) wait for safe and crucial function to be weighed particularly should. The risk in be the whole lifecycle that drops a car and system are potential breakdown, global superintendency orgnaization is aimed at drive automatically car (AV) and ADAS technology carry out stricter safe level stage by stage. This one trend drove functional security principle to be carried out mediumly in whole development process, include to design and be made of semiconductor.

A crucial design that functional security is car system thinks, to apply the brake, change direction and advanced drive support system (the safe and crucial function such as ADAS) is weighed particularly should. The risk in be the whole lifecycle that drops a car and system are potential breakdown, global superintendency orgnaization is aimed at drive automatically car (AV) and ADAS technology carry out stricter safe level stage by stage. This one trend drove functional security principle to be carried out mediumly in whole development process, include to design and be made of semiconductor.

The target that follows functional security and standard still can promote car man-machine the interface (the security of HMI) and dependability, cover the aspect such as high-end number cockpit, dashboard and service of Che Zaixin news. Current compositive number cockpit is in ceaseless gradual progress, they by single region controller drive, system, join accuses in controlling dashboard, recreation, look up monitor (the many monitor such as the function of HUD) and driver that monitor.

Region controller is many more integrated the electron controls unit (ECU) , offer more powerful CPU and GPU to calculate force, promotion drives experience, enhance security at the same time. This kind compositive the method that change can reduce systematic cost not only, simplify OTA software replaces technological process, and decreasing weight is measured and reduced power comsumption respect to also obtain remarkable result. To electric car, this especially important.

The support of environment of much monitor HMI of car interior accuses advanced and join of system, cloud, safe function and Che Zaixin in digital speech assistant, dashboard, recreation the function such as news service. No matter be to search the cafes around, still head for destination along optimal course, the design of newest number cockpit that is based on region controller can ensure car control and navigation safety are efficient. Region controller still offerred prominent figure to experience for commercial vehicle, for example, enhanced the function of intelligent electron rearview mirror for drawing trailer, bus and other line-haul car.

Choose appropriate applied processor platform, ensure functional security closes compasses

I.MX 95 of favour wisdom riverside should face region controller to apply with processor, easily deploy, in can assisting car manufacturer and one class supplier to be designed in its car HMI, contented function security closes compasses. Favour wisdom riverside issues set of processor of I.MX 95 application, its design is based on ISO26262 and standard of IEC61508 function safety to wait for automobile safety guideline.

Specific and character, i.MX 95 processor aims to satisfy ISO26262:2018 with systematic capacity (the automobile safety order and degree that SC)-3 provides (ASIL)-D system and ASIL-B wear compose index randomly, and IEC61508:2The function of 010 regulations brings congruent level (SIL)-2 wears compose index randomly. Trust to asking the compose in the applied setting of functional security is built and promote adopt, the ISO26262 that I.MX 95 plans to obtain D of ü of T ü V S adds up to compasses attestation, this is the independent attestation orgnaization with an accepted international, it is the standard of security set lowest of structure and electric product technically.

To help development personnel achieves functional security goal, i.MX 95 series has real time to install macrocosm, aim to become independent to move at the other part of processor. Function of this kind of safe region can ensure safe and crucial operation can be in manage with quality (in the environment that QM) application keeps apart, reliable and can forecast the ground to carry out, although be in,safety also can hold this one property in crucial harsh car environment. I.MX 95 processor is compositive and safe region framework, built the platform of advanced car HMI that enhances safe function to provide solid basis for compose.

I.MX 95 processor regards the number of region controller as cockpit and dashboard, can show through alarm warning sow a newspaper, communicate unusual situation to the driver, ensure the safe and crucial function of the car gets protective. The Gao Ke that alarm of the frequency inside this kind of warning and car accords with car manufacturer to ask relies on standard of gender and safety.

Realize 0 accidents to wish scene from the design safer car begins. The function of extensive automobile safety that understands processor of I.MX 95 of favour wisdom riverside to offer.

Be a center with the client piece go up systematic design

Favour wisdom riverside piece on the functional security solution that systematic technology uses I.MX processor to develop innovation for the client offerred powerful potential. This kind of method that is a center with the client pays attention to what blend in systematic level in every phase that semiconductor designs to think, only then the requirement that understands a client at profundity and the requirement that use finally. Through using piece on the system devises a method, the semiconductor solution that favour wisdom riverside offers can answer the client’s current requirement quickly not only, still have but sex of the look up before expansibility, flexibility is reached, the abidance that can get used to market demand the emerge in large numbers of gradual progress and new technology.

In addition, piece on the system is designed through simplifying hardware is mixed the cost of software and complexity, promoted I.MX the value of processor greatly, and aggrandizement the crucial function security that develops the SEooC that uses in the process in I.MX is characteristic. Method of this kind of design still can be endowed with can development of favour wisdom riverside deploys proper and safe relevant intellectual property inside framework of buy pedestrian island, contented and burgeoning systematic level function brings the demand of full-court scene.

The car function security that I.MX sustains is used exemple

Processor of I.MX 95 of favour wisdom riverside and photograph of IC (PMIC) of power source management are united in wedlock, compose built a general platform, the system of security of of all kinds automobile that develops a concept to use SEooC only and design:

• Digital cockpit, dashboard and HUD

• The driver monitors a system (DMS)

• Alarm of the frequency inside the car

• Backsight is photographed like the head

• Dynamoelectric rearview mirror

• The car carries news service and join

• Other and custom-built safe solution

Carried the custom-built and safe solution of processor of I.MX of favour wisdom riverside

Favour wisdom riverside provides comprehensive safe software, help client establishs functional security base for car application. Favour wisdom riverside can provide safe software framework (SAF) , system government implement (self check of kernel of SysMan) , structure (the safe software library such as SCST) , ensure fundamental software satisfies the safe requirement of ASIL-B attestation. Regard SafeAssure as the one part of the plan, favour wisdom riverside still offerred a series of safety application that are based on a service to support, include layer of abstraction of safe small controller (MCAL) and real time driver (RTD) .

The safe software library of favour wisdom riverside devotes oneself to to pass attestation of D of ü of T ü V S, follow standard of safety of the following function:

• ISO26262:2018 ASIL-D

• IEC61508:2010 SIL-3

• Support the hardware index of ASIL-B/SIL-2
