SVME7447a is an MPC7447a based single board VME computer for networked industrial control system. The SVME is built around MPC7447a and Tsi107; the mpc7447a is a high performance RISC engine from Freescale semiconductor, with built-in SIMD unit called AltiVec technology. Tsi107 is a powerful host bridge for PowerPC CPU from tundra semiconductor with SDRAM controller, PCI bus and clocking interface.


This board has been designed to integrate the most required functions, including Ethernet controller, serial communication ports and flexible custom security IP implementation features.
