ABSTRACT:
A data processing device comprising a clock generator for producing pulses establishing instruction cycles, a memory accessible by assertion of addresses, an instruction decode and control unit, having an instruction register operative to hold a program instruction, operative to decode a program instruction providing control signals according to a pipeline organization to control the operations of the data processing device within each instruction cycle and to initiate a block sequence responsive to an instruction code representing a block instruction. A program sequencer circuit, having a program register to hold a program count corresponding to a program address, is operative to access the memory with the contents of the program register to obtain the program instruction corresponding to the program address. Further included is an arithmetic logic unit operative to perform an arithmetic operation on data received by the arithmetic unit and to combine the contents of the program register with a data field decoded from the block instruction by the instruction decode and control unit to generate a block end address, and a block handler unit, having a block start register operative to store the contents of the program register, is responsive to the control signals from the instruction decode and control unit to store the program address corresponding to the block start address to the block start register wherein the contents of the block start register correspond to a start address for a block of instructions to be executed. Other devices, systems and methods are also disclosed.
