Future trends and main growth points of DSP

The demand for high-speed and high-density data processing is constantly challenging the performance limits of DSP. In the future, DSP technology will present five major development trends:

The integration of DSP requires more and more devices to embed DSP functions, including DSP cores or hardware DSP units.

With the increase in real-time algorithm complexity, the demand for more word length and larger dynamic range, the shortening of product development and market time, and the continuous decrease in floating-point algorithm costs, the conversion of DSP fixed-point algorithms to floating-point algorithms is being driven.

Low power consumption. DSP is not about achieving better computational performance, but rather pursuing a balance between performance and power consumption. In many application scenarios, the heat dissipation of the system is crucial, so we cannot blindly pursue high main frequency or multi-core, and more importantly, we need to balance low power consumption requirements.

In the era of the Internet of Things, DSP's demand for software IP protection and secure network connections is constantly increasing, and in the future, it will pay more attention to security features.

Due to the faster product iteration, downstream customers need to manage more and more code. At the same time, customers also face more challenges in system integration, testing, and debugging. The key points that DSP needs to consider in future design will be more diverse.
