PCIe Bridge Hardware for Gen-Z Memory System

As applications requiring a lot of memory grows, memory-centric computing systems which has a lot of memory pool are drawing attention. And the high-speed interconnection for accessing memory pools in this system is a very important part. In this paper, the bridge hardware for connecting PCI Express bus which is widely used in general systems, to Gen-Z protocol adapter which is one of the new high-speed networks, is shown, and its maximum performance is measured. This hardware has shown that it can support up to 720MB/s for memory writes and 3.5GB/s for block writes. This bridge hardware is expected to upgrade the performance of existing hardware and can expand the application field of the Gen-Z memory system.
