AHB Multi Fabric

The AHB Fabric provides the necessary infrastructure to connect up to 16 shared AHB Slaves to up to 16 AHB-Lite Bus Masters.

Overview

The AHB Fabric provides the necessary infrastructure to connect up to 16 shared AHB Slaves to up to 16 AHB-Lite Bus Masters. The off-the-self configuration support 4 AHB Masters and 7 AHB Slaves and includes a remapping selection.

In a typical AHB system, several AHB Masters may compete for a shared (AHB) bus; a bus arbiter determines bus ownership. The AHB Fabric allows for the various AHB-Lite Masters to connect to several different shared peripherals without the need to arbitrate for a shared AHB bus. Instead, arbitration is performed at the peripheral. This way, the various Masters may see a significant increase in performance over a standard AHB system. However, systems where multiple masters need frequent access to the SAME peripheral will see only a modest performance increase.

The Fabric may be connected to the remainder of the subsystem as follows. Each of the AHB Fabric’s M Mirrored Slave Ports is connected to an AHB Slave module (e.g. External Bus Interface, Memory Controller, AHB-to-APB Bridge). On the Master side, each of the N-1 AHB Fabric’s Mirrored Master Ports is connected to either the output side of an AHB Arbiter (in the case where each AHB system has multiple bus Masters) or directly to an AHB or AHB-Lite Master such as a microprocessor.

Secure Multi-Path Routing with All-or-Nothing Transform for Network-on-Chip Architectures

Ensuring Network-on-Chip (NoC) security is crucial to design trustworthy NoC-based System-on-Chip (SoC) architectures. While there are various threats that exploit on-chip communication vulnerabilities, eavesdropping attacks via malicious nodes are among the most common and stealthy. Although encryption can secure packets for confidentiality, it may introduce unacceptable overhead for resource-constrained SoCs.

Why verification matters in network-on-chip (NoC) design

In this article, we will dive deeper into a comprehensive methodology for formally verifying an NoC, showcasing the approaches and techniques that ensure our NoC designs are robust, efficient, and ready to meet the challenges of modern computing environments.

SoC design: When a network-on-chip meets cache coherency

Many people have heard the term cache coherency without fully understanding the considerations in the context of system-on-chip (SoC) devices, especially those using a network-on-chip (NoC). To understand the issues at hand, it’s first necessary to understand the role of cache in the memory hierarchy.

Accelerating RISC-V development with network-on-chip IP

In the world of system-on-chip (SoC) devices, architects encounter many options when configuring the processor subsystem. Choices range from single processor cores to clusters to multiple core clusters that are predominantly heterogeneous but occasionally homogeneous.

Network-on-chip (NoC) interconnect topologies explained

Today’s complex system-on-chip (SoC) designs can contain between tens to hundreds of IP blocks. Each IP block may have its own data width and clock frequency and employ one of the standard SoC interface protocols: OCP, APB, AHB, AXI, STBus, and DTL. Connecting all these IPs is a significant challenge.
