Abstract (en)
[origin: WO03060721A2] The invention relates to a method and a system for writing NV memories in a controller architecture, in addition to a corresponding computer program product and a corresponding computer-readable storage medium, which can be used in particular to accelerate writing or programming operations in NV code memories of microcontrollers, such as e.g. smartcard controllers. The method consists of extending the instruction set of the controller by MOVCWR (move code write) instructions, which allow a defined data item (byte) to be written to a defined target address in an NV code memory. The data item (byte) is written to the correct position of the cache page register of the relevant NV memory and the page-address pointer register of the memory is updated with the corresponding page address. If an MMU (Memory Management Unit) is present, the MOVCWR write operation to the cache page register, in addition to the MOVC read or code fetch operation are controlled by said MMU.
