Overview

This PCI Host Bridge IP core enables data transfers between a host processor and PCI bus based devices. 

The bridge allows the host to initiate PCI accesses or to respond to transactions initiated by other PCI devices.

The core complies with the PCI bus specification versions 3.0 and 2.3, and can act as a PCI master and target. Furthermore, it implements PCI bus arbitration, supporting up to seven PCI bus agents, PCI reset signal generation, and all types of PCI transactions provisioned by the standard. 

The PCI-HB builds on more than 15 years of CAST PCI IP expertise and has been designed for straightforward reuse, with proven design practices that ensure easy integration and smooth technology mapping. The core is available in synthesizable RTL or as a targeted FPGA netlist, and is delivered with everything required for rapid and successful integration and implementation.

Moving to AMBA® 5? Your AMBA® 4 IP Can Still Come With You

As SoC architectures adopt AMBA® 5 fabrics and components, many proven IP blocks still rely on AMBA® 4 or earlier interfaces. That creates a common integration problem: how do designers connect newer AMBA® 5 system components to existing IP without redesigning the IP or replacing verified blocks?

8051s in Modern Systems: Interfacing to AMBA Buses

Despite being 40 years old, 8051 microcontrollers can still serve useful roles in modern systems. But integrating 8051s in today's systems with their de facto standard AMBA® buses, wider datapaths, and shared memories can seem impossible. Yet it can be done. Here we take a look at the challenges, and how to overcome them.

A comparison of Network-on-Chip and Busses

This whitepaper summarizes the limitations of traditional bus-based approaches, introduces the advantages of the generic concept of NoC, and provides specific data about Arteris’ NoC, the first commercial implementation of such architectures
