CCI-550

Today ARM announces two new additions to its CoreLink system IP design portfolio, the CCI-550 interconnect and DMC-500 memory controller. Starting off with the CCI announcement, we find the third iteration of the Cache Coherent Interconnect. The CCI is the cornerstone of ARM’s big.LITTLE strategy as it provides the required cache-coherent system interconnect between CPU clusters and other SoC blocks such as the main memory controllers and thus enabling heterogeneous multiprocessing between all the IP blocks. The CCI-550 is an improvement to the CCI-500 which ARM announced back in February among other IPs such as the new Cortex A72 core design. Both the CCI-500 and the new CCI-550 are generational successors to the CCI-400 that is found in all currently released big.LITTLE SoCs such as...
