Abstract

To program the device during running of a computational process in device electronics, the device having an activated first memory area storing a first programmable configuration and a deactivated second memory area storing a second programmable configuration. The second programmable configuration is modified. Simultaneously, the first programmable configuration in the first memory area is executed by the computational process. Upon completion of configuring the second memory area, the first memory area is deactivated and the second memory area is activated for executing by the computational process.
