详细介绍

DNDPB_S327
Monster's Mailman
HPC Peripheral featuring Altera Cyclone III FPGAs
Hosted via 10/100 base-T Ethernet

Overview

Designed for high performance computing applications, the DN_DPB_S327 is an FPGA-based peripheral that allows algorithm developers to employ hardware-in-the-loop acceleration utilizing a large grid of 27 cost effective, Altera Cyclone III FPGAs. Data movement to/from the FPGA grid is accomplished via 10/100 base-T Ethernet. We have several chassis configurations that can fit up to 20 of these cards in a single 19" rack. Contact the factory for details.

The FPGAs: 27 Altera Cyclone III

The 3C120 from Altera's Cyclone III family is utilized and this is the second largest member of this cost effective (read: CHEAP) family. The Cyclone III FPGA family has an impressive price/performance ratio for hardware-in-the-loop accelerators, with device power consumption much lower than the higher performance FPGA families.

Features of Cyclone III include an efficient, 4-input look-up table (LUT) logic, 9 Kb (2 x 9 Kb) block RAMs, along with 18 x 18 multipliers. We use the FF484 package, which gives us the highest possible circuit board density. 100% of the FPGA resources are dedicated to your application. The 27 FPGAs have the identical pinouts and can be configured with the same file, eliminating the time consuming task of optimizing the same design for 27 different pinouts. The FPGAs can be configured with different functionality and programmed separately.

FPGA configuration files can be stored on the board in a 64Gb NAND FLASH, but the most likely usage model is to have the host system store and orchestrate FPGA configuration.

We do not supply simulation, FPGA synthesis, or place/route. But expensive, third-party synthesis tools are not needed and no longer required to get good quality of results. In truth, the cost effective Quartus®II tools available directly from Altera have proven in benchmarks to be superior to the expensive third party tools.

An on board ARM9 processor

An AT91SAM9G20 AT91 ARM Thumb microcontroller runs an ARM9 processor at 400MHz. This processor boots to LINUX. Source and ‘C’ examples under a GPL license are provided. 100% of the processing power of this microcontroller is dedicated to your application. 64 megabytes (16M x 32) of external SDRAM is stuffed standard, along with a 64 Gb NAND FLASH. Processor code can reside in the NAND FLASH at boot, or downloaded via Ethernet. Data movement to/from the 27 Cyclone III FPGAs is aided by a Config FPGA (Cyclone II 3C16).

Debug

A JTAG connector provides an interface to SignalTap and other third party debug tools
