Enabling CXL in Heterogeneous Compute with Arm | Utilizing Tech Episode 3×13

Although the emergence of CXL in server CPUs is big news, the inclusion of this technology in Arm processor IP is just as important. In this episode of Utilizing CXL, Eddie Ramirez of Arm joins Craig Rodgers and Stephen Foskett to discuss CXL in the ARM-powered ecosystem. Arm develops processor IP that is used in CPUs as well as supporting processors throughout the datacenter. We begin with a discussion of CXL 1.1, which brings memory expansion to Arm CPUs. But Arm is also delivering CXL 2.0 which would allow memory pooling to increase the utilization of memory, and thus overall system efficiency. The next step is true heterogeneous compute, with accelerators like GPU and DPU sharing memory with CPUs in a flexible fabric that can leverage CXL.
