Data processing unit

From Wikipedia, the free encyclopedia

A data processing unit (DPU) is a programmable specialized electronic circuit with hardware acceleration of data processing for data-centric computing.[1] The data is transmitted to and from the component as multiplexed packets of information. A DPU generally contains a CPU, NIC and programmable data acceleration engines.[2][3] This allows DPUs to have the generality and the programmability of central processing units while being specialized to operate efficiently on networking packets, storage requests or analytics requests.[4][5][6]

The data acceleration engines 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 than an SIMD architecture (required as each request needs to make different decisions and follow a different path through the chip).[7][8] DPUs can be either ASIC-based, FPGA-based or SoC-based.[9] DPUs have been increasingly used in data centers and supercomputers since their introduction in the 2010s due to the rise in use of data-centric computing, big data, security, and artificial intelligence/machine learning/deep learning.[10] DPUs are designed to be independent infrastructure endpoints.[11]
