Write scalable and tunable implementations of DSP algorithms in high-level languages like C, Python and Matlab, as well as low-level languages like fixed-point assembly. Tailor DSP algorithms to extract maximum performance based on the choice of platforms that support either floating-point or fixed-point arithmetic. Engineer solutions to deal with precision headroom issues commonly encountered while implementing audio processing solutions on fixed-point hardware platforms. Use knowledge of DSP techniques like correlation, pitch detection, frequency transforms, noise shaping and fundamentals of C programming to implement DSP features. Use a knowledge of Mathematics and DSP to optimize DSP algorithms. Analyze filter structures and related kernels to increase execution speed, save memory, and allow vectorized implementations of the DSP algorithms. Develop memory maps for DSP applications, making decisions related to the associated trade-offs between the execution speed and memory required by the C implementation. Identify and utilize hardware capabilities to optimize runtime software performance. Plan work to deliver software features, informed by an understanding of the underlying hardware and its interconnections. Profile algorithm implementations with the help of tools available in the development environments for the platforms. Additionally, develop methods to extract detailed information on the resource consumption to support other hardware teams in making decisions around power management. Aid the QA teams by developing stimulus signals and test cases to test and debug at integration and validation levels.
