To that end, we re removing non-inclusive language from our products and related collateral. We velaunched an internal initiative to remove language that could excludepeople or reinforce historical biases, including terms embedded in oursoftware and IPs. You may still find examples of non-inclusivelanguage in our older products as we work to make these changes andalign with evolving industry standards.

7 This device-wide infrastructure is a high-speed, Integrated data path with dedicated switching. The NoC can be logically configured to representcomplex topologies using a series of horizontal and vertical paths and a set of customizablearchitectural NoC was designed for scalability. It is composed of a series of interconnected horizontal(HNoC) and vertical (VNoC) paths, supported by a set of customizable, hardware implementedcomponents that can be configured in different ways to meet design timing, speed and logicutilization HNoC and VNoC are dedicated, high bandwidth paths connecting Integrated blocksbetween the processor system and the Programmable logic (PL) without consuming largeamounts of Programmable NoC supports end-to-end quality of service (QoS)

8 To effectively manage transactions andbalance competing latency and bandwidth requirements of each traffic NoC components comprise NoC master units (NMU), NoC slave units (NSU), NoC packetswitches (NPS), and NoC Inter-Die-Bridge (NIDB). The NMU is the traffic ingress point; the NSUis the traffic egress point. All IPs have some number of these master and slave connections. TheNIDB connects two super logic regions (SLRs) together, providing high bandwidth between NPS is the crossbar switch, used to fully form the 2: OverviewPG313 ( ) November 8, 2021 ACAP Programmable NoC and Integrated Memory controller 6 Send FeedbackHorizontal versus Vertical NoCAs shown in the following figure, NoC paths partition into Horizontal NoCs (HNoCs) and VerticalNoCs (VNoCs).

9 The HNoCs are placed on both the bottom and top of the die. There are four bi-directional physical NoC channels in HNoC. While the bottom HNoC has four bi-directionalphysical channels in all devices, in the Prime and AI series devices the top HNoC has only two bi-directional physical channels. The bottom HNoC typically connects to a selection of blocks suchas PS, PMC, CPM, and DDRMC ( Integrated DDR Memory controller ) to list a few. The PS, PMC,and CPM are collectively referred to as Control, Interfaces and Processing System (CIPs). TheHNoC consists of NoC components (NMU, NSU, NPS, and more). Similarly, the top HNoCtypically connects to a selection of blocks such as DDRMC.

10 For SSIT devices, the top HNoCconnects to NoC Inter-Die Bridge (NIDB) providing high bandwidth between two VNoC refers to the vertical NoC column. There are two bi-directional physical NoC channelsin the VNoC. Each Versal device could have more than one VNoC.
