The use of FPGA technology enables us to provide boards containing fully functional, tested examples of the newest Arm processors before any hard silicon devices are available from a foundry.

It is usual for an SMM to be constructed from one or more LogicTile Express boards. A SODIMM memory module is generally included, to provide the system SDRAM since this is not on the motherboard.

An SMM behaves like a Versatile Express CoreTile, which allows it to be mounted on the V2M-P1 motherboard for use as an off-the-shelf development system. PLLs in the FPGA are used to give the highest possible CPU speed for an FPGA implementation. As it is a drop in replacement for a CoreTile Express board, only a single set of off-board AMBA AXI buses are implemented.

SMMs are available in the Versatile Express range for the following Arm processors:
