PCT No. PCT/EP93/03498 Sec. 371 Date Aug. 22, 1994 Sec. 102(e) Date Aug. 22, 1994 PCT Filed Dec. 10, 1993 PCT Pub. No. WO94/15287 PCT Pub. Date Jul. 7, 1994A multitasking controller comprising task storage means (2) for storing up to N tasks (P0,P1,P2,P3) each comprising a sequence of instructions, a microprocessor for processing, by time-sharing, a plurality of such N tasks, and a random access memory (12) for storing variable data created and used by said microprocessor. The microprocessor further comprises a scheduler (7) realized in hardware for controlling the use of said microprocess or by such processes, and program counter storage means for storing N program counters (Pc0,Pc1,Pc2,Pc3) each for use by the scheduler (7) is able select a different one of the program counters (Pc0,Pc1,Pc2,Pc3) when the task processed by the microprocessor is changed without the transfer of data from the random access memory (12).
