Abstract
A device generates an address branch trace for a microcontroller unit, a microprocessor or a data processing unit having a set of instructions including at least one predicated instruction and at least one instruction of the expanded type. The device includes: a first block to receive a first signal representative of an actually executed instruction; a second block to receive a second signal representative of an expanded instruction; a third block to receive a third signal representative of a discontinuity branch between a source address and a destination address of a program executed by the microcontroller, microprocessor or data processing unit; at least one register to store consecutive addresses pointed to by a program counter; a fourth block to process the first, second and third signals in order to determine a pair having a source address and a destination address for an address branch, when appropriate; and a storage unit to store said address pair.
