ABSTRACT:
The invention relates to a digital signal processor with a RAM (random-access memory) having its output connected to a first input and, through a first temporary storage device to a second input of a multiplier, with an adder following the multiplier, and with a clock device for controlling data-word transfers. The speed of the processor is increased by connecting a second auxiliary storage device between the RAM and the first input of the multiplier and providing a first switching element via which the RAM and the second temporary storage device are connectable to the first input of the multiplier.
