Processing Elements / Data Processing Units

• A Processing Element (PE), also called a Data Processing Unit (DPU), is the fundamental building block of a systolic array.
• Each PE is designed to perform simple operations such as:
• Addition
• Multiplication
• MAC (Multiply–Accumulate)
• PEs are connected to their neighbors in a regular pattern, allowing data to flow step by step.
• Together, many PEs work in parallel to achieve high throughput in matrix and vector computations.
