8. Key Performance and Memory Consumption Data
8.1. Key Performance Metrics
Note
Driver performance depends on its configuration. In these cases, the drivers are configured to achieve maximum performance with Functional Safety mechanisms disabled.
Performance is also dependent on the overall system architecture and runtime environment. We have achieved best performance for driver by focusing on a single module.

8.2. Memory Footprints
Note
The memory footprint values represent only the module-specific driver sections for each example. These are calculated by extracting module-specific memory sections from the build output and categorizing them into standard memory types: .text (code), .data (initialized data), .bss (uninitialized data), and .rodata (read-only data). Memory measurements are captured in bytes with the optimization level set to O2.
