Abstract
The present invention relates to a pipeline microprocessor (MP , MP ) comprising a program counter (PC), means (MUX, ADD) for the incrementation of the program counter (PC), instruction decoding means (PREDEC, DEC , DEC , DEC ) comprising means (PREDEC) to decode a conditional jump instruction (JMPc) of the program counter, a bank of registers (REGBANK), a computation unit (ALU) comprising a first output (S ) to deliver a result and a second output (S ) to deliver status bits (C, N, P, Z) of the result. According to the invention, the computation unit (ALU) and the means (PREDEC, DEC ) for decoding the conditional jump instruction (JMPc) are laid out in two neighboring pipeline stages (ST , ST ), and the means (PREDEC) for decoding the conditional jump instruction (JMPc) are connected to the second output (S ) of the computation unit (ALU).
