ABSTRACT:
A data converter for converting a signal either from analog form to digital form or from digital form to analog form includes a storage register. The storage register receives and temporarily stores digital data samples. The digital data samples are transferable out of the storage register in the same sequence in which they were received. A digital signal processor coupled to the storage register is interruptible to transferred digital data samples either to or from the storage register. In this manner, the digital signal processor transfers multiple digital data samples either to or from the storage register during each interrupt rather than transferring a single data sample per interrupt, thereby reducing the number of interrupts necessary to transfer a given number of digital data samples.
