COMING UP
It is known that in the future DSPs will become much faster. It is expected that by the turn of this century, a 200 MIPS equipment will be common with 300- to 400-MIPS machines available in the year 2001. A conventional 64-kbit/s voice signal can be produced in a high-quality manner by the use of a 2-MIPS machine and the ITU-T is examining a standard for a 4-kbit/s voice signal which is expected to require 40–45 MIPS. The processor to support this low-bit rate coder is on the way and likely to be announced in 1999 or 2000.
Furthermore, PCs and workstations will have DSPs installed (or a new generalized chip that performs well enough to produce low-bit rate and high-quality audio signals), thus providing for toll-quality signals from ...
