ABSTRACT:
A digital pattern generator generates various kinds of digital pattern signals. A first memory stores an execution signal, an area control signal and a digital pattern. A program counter generates a first address signal in accordance with the execution signal read from the first memory and a first clock signal, and the first memory is addressed by the first address signal. Thus, the pattern generator operates as a microprogram type generator. A second memory includes a plurality of memory areas each storing a digital pattern, and a capacity of each the memory area corresponds to that of the first memory. When the second memory is addressed by a second address signal from an address counter, the pattern generator operates as a sequential type generator. When the memory area of the second memory is selected by the area control signal read from the first memory and the selected memory area is addressed by the first address signal, the second memory acts as an auxiliary memory of the first memory.
