Major architectural blocks of both the SA8775P and SA8255P include:
Qualcomm Kryo Gen-6 CPU built on Arm V8.2 Cortex technology
Qualcomm Adreno 663 GPU for the highest in graphics performance and power efficiency as well as safe general-purpose (GP) GPU compute support
Qualcomm Hexagon Tensor Processor integrated with Qualcomm Hexagon DSP, quad Qualcomm Hexagon Vector eXtensions (HVX) processor, and dual Qualcomm Hexagon Matrix eXtensions (HMX) co-processors for high performance machine learning use cases.
The SA8775P is the next-generation Qualcomm Snapdragon Advanced Driver Assistance System (ADAS) and automotive infotainment SoC designed for superior performance and power efficiency in automotive applications. Designed with Safety Element Out of Context (SEooC), the SoC targets ASIL D use cases. Automotive Safety Integrity Level (ASIL) D is the highest rigor applied to safety assurance.
The SA8255P delivers next-generation Qualcomm Snapdragon automotive infotainment SoC designed for superior performance and power efficiency. Developed with SEooC targeting ASIL B use cases, the SAM8255P empowers automakers with scalable solutions that are connected, smart, and aware.
