1 Overview

1.1 Introduction

The ADLINK PCIe-ACC100 (also knows as PCIe-A100) is a single-slot eASIC FEC

accelerator server adapter based on the Intel® vRAN Accelerator ACC100 adapter. The

PCIe-ACC100 can be deployed in various Xeon-based COTS servers ranging from dual-

socket Xeon-SP rackmount implementations, single socket Xeon-SP edge servers through to

low-core-count (LCC) based Xeon-D servers.

The main features of the PCIe-ACC100 are summarized as follows:

•Integrates Intel® vRAN Dedicated Accelerator ACC100

oLDPC FEC processing (3GPP 5G): LDPC encode/decode, CRC, rate matching,

HARQ

oLTE FEC processing (3GPP 4G): Turbo encode/decode, CRC, rate matching

oSupports virtualization, scalable to desired system configuration; separate engines for

UL/DL

oLoad balancing supported by Queue Mgr.

•Low profile PCIe card for low-cost design

oPower envelope of low-profile slot

oFor Intel Xeon Scalable Processor & Xeon D Processor based COTS servers

oNo PCIe card auxiliary power required

oNo front-panel I/O for maximum air-flow

oFull and Half-height bracket options

•Onboard DDR4 for HARQ processing

•High-speed host interface: PCIe x16 Gen3

•Operation temperature: -5°C to +55°C

•Passive cooling

•NEBS compliance ready

3 Testing the Module

1. OS:

Install an operating system such as Ubuntu 20.04. Login and switch to user “root”

(su root). Make sure this server is connected to Internet.

2. Copy files:

Copy the file test-bbdev.tar.gz to /home and unpack it.

3. Update the grub:

Update the grub to improve the performance.

1. Execute the command "vi /etc/default/grub"

2. Paste the following text:

GRUB_CMDLINE_LINUX="default_hugepagesz=1G hugepagesz=1G

hugepages=8 nmi_watchdog=0 selinux=0 isolcpus=1-7,9-15 nohz_full=1-7,9-15

rcu_nocbs=1-7,9-15 intel_pstate=disable nosoftlockup"

3. Execute the command "update-grub"

4. Execute the command "reboot"

4. Configure the test-bbdev environment:

./test-bbdev_env_setup.sh

The configuration is successful when you see the following.
