1.17. Hard Processor System (HPS)

The Intel® Agilex™ SoC Hard Processor System (HPS) is Intel’s industry leading third generation HPS. The HPS is a quad-core Arm* Cortex* -A53, which allows users to easily migrate existing SoC designs from Intel® Stratix® 10 SoCs to Intel® Agilex™ SoC.

The HPS also enables system-wide hardware virtualization capabilities by adding a system memory management unit. These architecture improvements ensure that SoCs meet the requirements of current and future embedded markets, including wireless and wireline communications, datacenter acceleration, and numerous military applications.
