Vector processing is a method used in computing to handle multiple data points simultaneously. Instead of processing one piece of data at a time, vector processors can perform operations on entire arrays or vectors of data. This approach significantly speeds up tasks that involve large datasets, such as scientific simulations and graphics rendering. Vector processors are often found in specialized hardware, such as graphics processing units (GPUs) and supercomputers. They utilize a set of registers to store vector data and execute operations in parallel, making them efficient for applications that require high-performance computing.
