Fourth Edition. John G. By using a modern DSP, you no longer need to hope that your audio gear will sound good, you can force it to at any time by having the electronics compensate for shortcomings. The key bit to understand is that you can build an execution unit to run one or several of the wide range of mathematical operations out there.
Simply packing in every possible option would be hugely wasteful in terms of size and power consumption. In a nutshell, a DSP is optimized for the most common tasks used in digital signal processing workloads. The list includes floating-point mathematics, the modulo operation, saturating arithmetic, multiply-accumulate MAC , and fused multiply-add FMA operations. These functions are often required in the filter, Fourier transform, codec encoding, and other DSP algorithms.
Digital signal processors are typically built to run a number of these operations in parallel a superscalar architecture for much faster processing with lower clock speeds than a typical CPU. The DSP handles the audio, such as decompressing music or activating your voice assistant. DSPs also use highly optimized memory systems. DSP memory architectures are optimized for this highly ordered data stream, unlike CPUs which use remappable blocks of memory where the specific location of a register is often less important.
As such, DSPs also rely heavily on direct memory access DMA , which moves data in and out of buffers at regular intervals without consuming processing time. They accelerate common DSP mathematical operations in hardware and boast specific memory architectures designed for real-time data streams. The net result is faster and more efficient processing of audio and some other data types. Many more high-profile companies are starting to embrace the transformative power of a properly-used DSP.
From accurately making 3D audio , to automatically optimizing music, to enabling the next generation of Bluetooth audio codecs , the increased amount of development in the DSP field is going to change how we listen in very stark ways.
