Flash accelerator delivers performance boost
STMicroelectronics has announced two advancements which it says improve the performance and power consumption of its STM32 range of mcus.
According to ST, the STM32 embedded Flash performance gets a double boost with the 90nm production availability and adaptive real time (ART) accelerator, enabling programme execution up to 120MHz.
A proprietory ART memory accelerator has been incorporated to balance the performance of the ARM Cortex-M3 over Flash memory technologies. ST says that the cpu can now operate up to 120MHz without waiting.
To release the processor's full 150 DMIPS performance at this frequency the accelerator implements an instruction pre-fetch queue and branch cache, designed to enable programme execution from Flash at up to 120MHz with zero wait states.
The new 90nm devices featuring the ART memory accelerator are sampling at lead customers.
