Patent ID: 8166283

Claim:
A generator of a first signal comprising: a memory in which instructions are stored, each instruction comprising a code portion and an argument portion; means for successively reading instructions stored in the memory; decoding means configured to receive, for each read instruction, the code portion of the instruction and of providing an activation signal which depends on the code portion; and means for providing said first signal configured to receive, for each read instruction, the argument portion of the instruction and configured, according to the activation signal having a first value, to store the argument portion and to provide said first signal equal to the argument portion and configured, according to the activation signal having a second value, to provide said first signal equal to a most recently stored argument portion, wherein the means for providing said first signal comprises: a multiplexer controlled by the activation signal and configured to receive, at a first input, the argument portion of the read instruction and, at the second input, said first signal; and an additional memory connected to the output of the multiplexer and providing said first signal, wherein the instructions are stored in the memory at locations each associated with an address, the generator comprising address provision means, read means configured to successively read the instructions stored at the locations associated with the addresses, the decoding means configured to, for each read instruction, provide the address provision means with control signals which depend on the code portion of the read instruction, the address provision means configured to provide the next address according to the control signals, and configured to receive at least one event signal generated outside the generator and, for determined control signals, configured to provide the next address when the at least one event signal is at a first value.
