Versal Adaptive SoC CPM Mode for PCI Express
- Bundled With:
- Vivado Design Suite
- License: End User License Agreement
Product Description
The Versal™ adaptive SoC CPM Mode for PCI Express® is a building block IP for high-bandwidth, scalable, and reliable serial interconnect based on the PCI Express specification. Designs that configure an available integrated block for PCI Express with DMA/Bridge and cache coherent interconnect (CPM) can realize a specific implementation of the PCI Express Base Revision 4.0 (CPM4) or the PCI Express Base Revision 5.0 (CPM5).
