Abstract
A serially addressable non-volatile storage device, specifically flash memory, is usable for recording digitally compressed audio by providing a software-controlled serial interface between a digital signal processor (DSP) and the storage device, and by storing sampled audio in a sample buffer, encoding and compressing the data, and directing it to an output buffer, and transferring the encoded and compressed data in uniformly-sized blocks to an alternate one of at least two flash buffers in the storage device. While one of the flash buffers is receiving encoded data, the other is used to store its contents in the flash memory in the background, thereby permitting uninterrupted data flow.
