An Effective RAM Accessing Method for PCM Processing Systems
An effective method to control RAM in PCM digital audio processors using VCR has been studies. The main functions of the RAM is to interleave/de-interleave data during recording and playback respectively, and to absorb time base error of data caused by jitter of VCR. Newly developed RAM control method (called corn type) can reduce the necessary RAM size to one-half that of conventional method.
