PS and PL Ethernet Performance and Jumbo Frame Support with PL Ethernet in the Zynq-7000 AP SoC
Srinivasa Attili, Sunita Jain · 2013
The focus of this application note is on Ethernet peripherals in the Zynq®-7000 All Programmable (AP) SoC. This application note describes using the processing system (PS) based gigabit Ethernet MAC (GEM) through the extended multiplexed I/O (EMIO) interface with the 1000BASE-X physical interface using high-speed serial transceivers in programmable logic (PL). This application note also describes the implementation of PL-based Ethernet supporting jumbo frames. The designs provided with this application note enable the use of multiple Ethernet ports, and provide kernel-mode Linux device drivers. In addition, this document includes Ethernet performance measurements with and without checksum offload support enabled.
