FIELD: data processing systems.
SUBSTANCE: data processing device has processing core, having bank of registers, which includes a set of registers, which are utilized for storing stack operands. Commands from second set of commands, determining stack operands, are translated by translator of commands to commands of first set of commands or controlling signals, appropriate for these commands, and determining register operands. These translated commands are then performed by processor core. Commands translator has multiple display states for controlling which registers match which stack operands in stack. Changes between display states are performed dependently on stack operands added to set of registers or removed from there.
EFFECT: improved system operation speed.
