A programmable unit includes a command execution unit for carrying out commands, a memory device for storing data required for command execution and data emitted from the command execution unit, and a buffer-storage device for buffer storing the data emitted from the command execution unit. The command execution unit writes to the buffer-storage device data to be transferred to the memory device. The data written to the buffer storage device is transferred to the memory device at a later time. The programmable unit is distinguished by forming the buffer-storage device as a stack, and/or by providing a control apparatus that, when required, causes data stored in the buffer-storage device to be moved temporarily to another memory device. Such a programmable unit can carry out any buffer storage of events that may possibly be required quickly and easily in all circumstances.

Programmable unit with a stack buffer storage device configurable into discrete shadow storage elements accessible by a plurality of command execution units

A program-controlled unit has a plurality of instruction-execution units for simultaneously executing successive instructions of a program that is to be executed. The program-controlled unit allows the number of access operations to a program memory storing the program that is to be executed to be reduced. The program-controlled unit has an assignment device which operates such that only the instructions for those instruction-execution units which are actually required for the execution of the program are stored in the program memory in which the program to be executed by the program-controlled unit is stored. The program includes a sequence of instructions which can be executed simultaneously. The assignment device allocates instructions that can be executed simultaneously to desired instruction-execution units for simultaneous execution, independent of each instruction's position within the sequence.
