The invention concern a multitasking controller comprising task storage means (2) for storing up to N task (P0, P1, P2, P3) each comprising a sequence of instructions, a microprocessor for processing, by time-sharing, a plurality of said N tasks, and data storage means (12), for storing variable data created and used by said microprocessor. The microprocessor further comprises a scheduler (7) realised in hardware for controlling the use of said microprocessor by said processes, and program counter storage means for storing N program counters (Pc0, Pc1, Pc2. Pc3) each for use by said scheduler (7)to control the instruction sequence of a separate one of said N processes, so that said scheduler (7) is able to select a different one of said program counters (Pc0, Pc1, Pc2, Pc3) when the task processed by said microprocessor is closed without requiring the transfer of data from said data storage means (12).
