Tomversations: Episode 11 – Data Processing Units (DPUs)

In the November episode of Tomversations, we’re going to take a look at the growing segment of Data Processing Units, or DPUs. These new I/O accelerators are not new. They’ve grown out of the market for intelligent Network Interface Cards (NICs) that incorporate on-board CPUs designed to increase throughput by accelerating networking traffic through something other than the main system CPU.

In this episode, Tom Hollingsworth takes us through the various types of chips that you might find in modern computing, from the workhorse x86 CISC chips favored by Intel to the specific ASICs and FPGAs that help in purpose-built devices. Along the way, Tom helps frame the discussion around DPUS and why they’re not just for networking traffic any more.
