Abstract
Various embodiments of the present invention are related to integrated circuits for processing data at a microcontroller interface. The microcontroller interfaces to a memory. The method is employed to process input data provided by the microcontroller during a memory write operation, or input data extracted from the memory during a memory read operation, respectively. A write/read control is used to indicate the memory write or read operation, and a logic address is translated to at least one physical address in the memory. The write/read control and the logic address are further employed to determine a data process mode. In various data processing modes, the input data are processed according to at least one of a plurality of data processing methods to result in processed data in different data formats. Data in different formats may be stored in various regions of the memory.
