CPU cache

The STM32CubeH7 demonstration takes benefit from Cortex-M7 performance:
•
16 Kbytes dedicated to instruction cache
•
16 Kbytes dedicated to data cache
Using the STM32H7 Series, the CPU load is decreased with video module from 87% to 5%
compared to STM32F7 Series, thanks to the hardware JPEG decoding and the support of
hardware conversion from YCbCr to RGB using Chrom-ART Accelerator.
