The LLK (Low Latency Kernel) compute functions are designed to optimize the performance of these units. However, understanding the relationship between the FPU/SFPU LLK compute functions and their corresponding init functions can be a daunting task. In this article, we will create a matrix of FPU/SFPU LLK compute functions and their corresponding init functions, providing a comprehensive guide for developers and architects.
