| Specification | Details | | :--- | :--- | | | 28nm FD-SOI (Fully Depleted Silicon On Insulator) by STMicroelectronics | | Total Compute Cores | 14 cores in total (4 CPU cores + 10 specialized accelerators) | | CPU Cores | 32-bit MIPS InterAptiv cores (5 total; 4x I-class, 1x M-class) clocked at ~1 GHz | | Vector Accelerators | 6x Vector Microcode Processors (VMP) : For mature, efficient vision tasks, proven in EyeQ2 and EyeQ3. | | Novel Accelerators | 2x Multithreaded Processing Clusters (MPC) : Versatile accelerators for complex vision algorithms, more energy-efficient than a GPU for specific tasks. 2x Programmable Macro Arrays (PMA) : Delivers compute density near that of fixed-function hardware but with full programmability. | | Memory Support | LPDDR4 memory; detailed specifications for power rails (e.g., DDR 1.1V) are available in official design guidelines. |
Designed from the ground up to meet ASIL (Automotive Safety Integrity Level) standards. Hardware failure detection mechanisms, such as error-correcting code (ECC) on all internal memories and registers, catch potential data corruption. eyeq4 datasheet
