摘要： An electronic device is provided, which includes a current supplying stage which is adapted to supply a first compensation current and a second compensation current to a first wire or a second wire, wherein the first compensation current is determined during a first clock period, when the first wire and the second wire are connected. The second compensation current is determined during a second clock period while the first wire and the second wire are not connected and the magnitude of the second current represents a ratio of a resistance value of the first wire and a resistance value of the second wire.

摘要： The invention is an electronic device including a ferroelectric random access memory (FRAM), a first supply voltage domain, a second supply voltage domain and a low drop output voltage regulator (LDO) receive a first supply voltage of the first supply voltage domain and providing a second supply voltage of the second supply voltage domain. The second supply voltage domain supplies the FRAM. The LDO switches between a first state providing and maintaining the second supply voltage of the second supply voltage domain and a second state providing a high impedance output to the second supply voltage domain. The electronic device switches the LDO from the first state to the second state in response to a failure of the first supply voltage domain.

摘要： A method for determining a physical address from a virtual address, wherein a mapping regulation between the virtual address and the physical address is implemented as hierarchical tree structure with compressed nodes. First, a compression indicator included in the mapping regulation is read, and a portion of the virtual address associated with the considered node level is read. Using the compression indicator and the portion of the virtual address, an entry in the node list of the considered node is determined. The determined entry is read, whereupon the physical address can be determined directly, if the considered node level has been the hierarchically lowest node level. If higher node levels to be processed are present, the previous steps in determining the physical address for compressed nodes of lower hierarchy level are repeated until the hierarchically lowest node level is reached.

摘要： An embodiment of the invention relates to an electronic device for processing interrupt requests. Interrupt requests that have the highest priority level are identified out of a plurality of interrupt requests. A priority word corresponding to a priority level is assigned to each interrupt request. The highest bit level of the bits at the most significant bit position of the priority words is identified. The bit level of the bit at the most significant bit position is compared with the highest bit level at this bit position. The priority words are then evaluated and compared consecutively and bit-by-bit. Priority words having a bit level at the respective bit position that corresponds to the highest bit level are further processed whereas priority words having a different bit level at the respected bit position are discarded.
