RD-V3-R1 Platform

Overview

RD (Reference Design) is a collection of resources to provide a representative view of typical compute subsystems that can be designed and implemented using specific generations of Arm IP.

RD-V3-R1 is a dual-chip platform in which two identical chips are connected through high speed CCG link. The CCG link is enabled through CMN S3 Coherent Multichip Link (CML) feature. RD-V3-R1 platform also supports the Realm Management Extension (RME). The RD-V3-R1 platform in particular has the following hardware configuration on each chip.

  • Upto 70xMP1 Neoverse Poseidon-V3 cores with Direct Connect and 2MB of dedicated, private L2 cache for each core.

  • 7 Shared LCP Groups, 10 AP cores per Shared LCP Group.

  • CMN S3 Revision 2 (CMN S3 R2) interconnect with 9x8 mesh network.

  • Multiple AXI expansion ports for I/O Coherent PCIe, Ethernet, offload

  • Arm Cortex-M55 processor for Runtime Security Engine (RSE) to support Hardware Enforced Security (HES)

  • Arm Cortex-M7 for System Control Processor (SCP) and Manageability Control Processor (MCP)

  • Arm Cortex-M55 processor for Local Control Processor (LCP) for local power management of each Application Processor (AP)

The Fixed Virtual Platform of RD-V3-R1 config supports dual chip with 14xMP1 Neoverse Poseidon-V3 CPUs per chip (2 AP cores per LCP Group)

The components integrated into this stack are described in Software Stack section.

Obtaining FVP

The latest version of the RD-V3-R1 fixed virtual platform (FVP) can be downloaded from the Arm Ecosystem FVPs page. On this page,

  • Navigate to “Neoverse Infrastructure FVPs” section.

  • Click on “Neoverse V3 Reference Design FVP” link to obtain the list of available Neoverse RD-V3-R1 Reference Design FVPs.

  • Select a FVP build under the section “Download RD-V3-R1” based on the host machine architecture.

    • For AArch64 host machine, click “Download Linux - Arm Host (DEV)” link.

    • For x86-64 host machine, click “Download Linux” link.

The RD-V3-R1 FVP executable is included in the downloaded installer and named as “FVP_RD_V3_R1”. Follow the instructions of the installer and setup the FVP. The installer, by default, selects the home directory to install the FVP. To opt for different directory than the one selected by the installer, provide an absolute path to that directory when prompted for during the FVP installation process.
