Understanding Signal Processing and DSP Chips
Signal processing refers to the manipulation, analysis, and interpretation of signals such as sound, images, and data to extract useful information. One of the key tools used in digital signal processing (DSP) is integrated circuits specially designed for offering extremely quick instruction sequences.
DSP chips are commonly used in applications that require a lot of mathematical calculations, such as multiply-and-add and shift-and-add. These chips can be found in a wide range of devices such as digital televisions, sound cards, fax machines, modems, hard drives, and cellphones.
The first commercial DSP chip was created by Texas Instruments and was used in the popular Speak & Spell game from the late 1970s.
