Cavium Coherent Processor Interconnect (CCPI') is an interconnect architecture designed by Cavium for their microprocessors.
Overview
CCPI is a cache coherent interconnect architecture designed by Cavium for their various microprocessors. CCPI is used to support symmetric multiprocessing on the ThunderX and ThunderX2 families.
Data Rates
| CCPI | CCPI2 | |
|---|---|---|
| Signaling Rate | 10 GT/s | 25 GT/s |
| Lanes/Link | 24 | 24 |
| Rate/Link | 30 GB/s 240 Gb/s | 75 GB/s 600 Gb/s |
| BiDir BW/Link | 40 GB/s | 150 GB/s |
