METHOD TO INTEGRATE ARM ECOSYSTEM IPS INTO PCI-BASED INTERCONNECT

摘要

Methods and apparatus for integrating ARM-based IPs in computer system employing PCI-based fabrics. An PCI-based fabric is operatively coupled to an ARM-based ecosystem employing an ARM-based fabric such as OCP, AHB, or BVCI via a corresponding fabric-to-fabric bridge. Transactions between IP operatively coupled to the PCI-based fabric and IP in the ARM-based ecosystem are facilitated by applying applicable ordering and conversions operations via the fabric-to-fabric bridge and/or fabrics. For example, posted writes originating from IP coupled to the PCI-based fabric are converted to non-posted writes and serialized via the fabric-to-fabric bridge and forwarded to the ARM-based ecosystem.

主权项

1. An apparatus comprising:
a first fabric comprising a Peripheral Component Interconnect (PCI)-based fabric to which a first plurality of Intellectual Property (IP) blocks are coupled; a second fabric comprising one of an Open Core Protocol (OCP) or an Advanced Microcontroller Bus Architecture (AMBA)-based fabric to which a second plurality of IP blocks are coupled; and a fabric-to-fabric bridge configured to facilitate transfer of data between the first fabric and the second fabric and configured to convert a posted memory write transaction originating from the first fabric into a non-posted memory write transaction and serialize the non-posted memory write transaction upon forwarding the transaction towards the second fabric.
