Разработка алгоритма записи данных, использующего стратегию двухуровневого разночастотного кольцевого буфера

Abstract

Automatic systems based on microcontrollers often use non-volatile memory with a limited lifespan for storing data. The limitation requires uniform use of memory cells. This can be provided by using a ring buffer strategy. However, classical ring buffer can't provide uniform use if there are several arrays in the memory which are updating with different frequencies. In this paper we introduce a data storage algorithm that uses a two-level multi-frequency ring buffer to ensure uniform wear of the memory.
