This post describes a recent in-vehicle ECU architecture, the Edge & Zone Architecture.

When I explain embedded C language functions, I classify them. In this post, I will explain the function classification.

This post describes the SW component configuration for each SW state that I recommend.

This post describes A- SPICE Software Engineering Process .3 (SWE.3) SW Detailed Design and UNIT Construction Detailed Process, which I recommend.

This post describes the A-SPICE Software Engineering Process.2 (SWE.2) SW Architecture Design detailed process that I recommend.

This post describes the A-SPICE Software Engineering Process.1 (SWE.1) SW Requirements Analysis detailed process that I recommend.

This posting describes SMP (Symmetric Multi-Processing) and AMP (Asymmetric Multi-Processing).

This post describes the watchdog timer.

With the recent development of SDV (Software Defined Vehicle), which is a hot topic, ECU architecture is shifting from domain architecture to edge architecture, zone architecture, and combined edge & zone architecture. OSS-ECAL is an OSS suitable for porting sensors, actuators, external memory, and other components associated with architectural changes.
