Data processing unit

A data processing unit (DPU) is a programmable electronic component that processes streams of data.[1] The data is transmitted to and from the component as multiplexed packets of information. DPUs have the generality and the programmability of central processing units but are specialized[2] to operate efficiently on networking packets, storage requests or analytics requests.[3][4]

A DPU differentiates itself from a CPU by a larger degree of parallelism (required to process many requests) and from a GPU by a MIMD architecture rather an SIMD architecture (required as each request needs to make different decisions and follow a different path through the chip).[5][6]
