HIGH-PERFOMANCE
ART Accelerator performance
Unleashing the full performance of the core beyond the embedded Flash’s intrinsic speed is an art. Combined with ST’s 90 nm technology, our
ART Accelerator™ achieves a linear performance up to 180 MHz, offering 225 DMIPS and 608 CoreMark performance executing from Flash.
The acceleration mechanism is made possible using a prefetch queue, a branch cache and a smart arbitration mechanism.
• MCUs using less advanced accelerators or
slower embedded Flash memories impact
execution performance as wait states
occur.
• MCUs using faster Flash but no branch
cache acceleration to achieve performance
usually show higher power consumption
as a result of more accesses to a
power‑hungry Flash.

Richer graphic and animations with ST Chrom-ART Accelerator
In applications using a display, graphical data generation can consume a lot of CPU bandwidth. To ofoad the CPU, a dedicated DMA has
been developed by ST to perform graphic content copy from the frame buffer (internal or external RAM) to the display interface (FMC or TFT
controller). This advanced graphic accelerator, the Chrom‑ART Accelerator, achieves a twofold increase in performance versus the CPU.
In addition to raw data copy, additional functionalities are supported such as image format conversion or image blending (image mixing with
some transparency).
