Abstract
A data processing system being constructed such that the amount of time a data bus of a data processor is occupied to perform predetermined data processing operations is reduced. The data processing system includes a data processor for processing data, a first memory for storing data, a second memory for storing data, a dedicated data processing circuit for performing a predetermined data processing operation on data, a data bus and first and second dedicated buses. The data bus is connected to said data processor and the first and second memories and transfers processed data from the data processor to the first memory and from the second memory to the data processor. The first dedicated bus is independent of the data bus and is connected to the circuit and the first memory and transfers processed data from the first memory to the circuit. The second dedicated bus is independent of the data bus, is connected to the circuit and the second memory and transfers data operated on by the circuit from the circuit to the second memory.
