MULTIPLE CONTROL STORES IN A PIPELINED MICROCONTROLLER FOR HANDLING NESTED SUBROUTINES

摘要

a micro controller to control a digital device without loss of clock cycles is formed of a plurality of memory control unit (20a, 20b, 20c).each of these memories is provided with a meter register (21a, 21b, 21c) to have access to different addresses in the memory of the corresponding command.in each clock cycle can have access to every memory instruction and a control register (22) is provided to receive a micro instruction from the control memoryselected.in this way, a micro instruction register, instruction is provided in every clock cycle even though the previous micro instruction is a conditional branch.a connection to a subroutine or a return to the instruction of the subroutine.in order to adapt the connection on the subprogramme and return instructions corresponding to the sub programme.the respective address of the subroutine is stored in a return stack (26) for presentation to a meter register mentioned above in order to select which is the reverse of the orderin which the addresses are placed at the top of the stack.
