Digital Signal Processing Handbook P49

Implementations of digital speech processing algorithms in software can be distinguished from those resulting from general-purpose algorithms basically in the type of arithmetic and the algorithmic constructs used in their realization. In addition, many speech processing algorithms are realized with Programmable Digital Signal Processors (PDSPs) as the software development target—this leads to important considerations in the languages and paradigms used to realize the algorithms. Although they are important topics in their own right, this section does not discuss the historical development of PDSPs to explain why these devices provide...
