Soft Macrocell Models for Versatile Express

Soft Macrocell Models for  Versatile Express Image (View Larger Soft Macrocell Models for Versatile Express Image)
A Soft Macrocell Model (SMM) is an FPGA implementation of an ARM processor, built with ARM development boards. The binary image is protected by the FPGA's built-in encryption mechanism, so the addition of any custom peripheral IP would require an extra LogicTile to be added to the development sytem.

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 PISMO2 or 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:

  • Early access to development hardware containing new ARM processor technology
  • Faster CPU speed than a typical software or hardware emulation
  • CoreTile SMM can be replaced with a hard silicon CoreTile Express equivalent when it becomes available. The LogicTile Express board can then be re-used for IP prototyping
