Hollybush2 is high performance, low power, DSP and general processing engine in a PC104 format. The large SpartanTM-3A DSP FPGA provides a programmable fabric capable of supporting several MicroBlazeTM, or similar, processor cores as well as custom DSP processing and general logic. Hollybush2 has both ISA and PCI PC104 interface support but either, or both, of these interfaces can be converted to being a custom high bandwidth interfaces.
For High Performance Computing ( HPC ) applications Hollybush2 boards can be stacked to form sequential, parallel, or combinational processing structures.
Hollybush2 can be used as a host processor board with standard PC104 cards as add-ons. Hollybush2 can support PCI grant/request cycles allowing bus mastering over the PCI interface.
Hollybush2 is capable of operating as a PCI to ISA bridge and vice-versa allowing the reuse of existing legacy ISA cards in PCI based systems or conversely allowing the use of new PCI based cards in legacy ISA based PC104 systems.
Hollybush2 is capable of operating as a stand alone board and can be supplied with short lead connectors to facilitate this mode of operation.
Board Features
FPGA
XilinxTM
XC3SD3400A
SpartanTM-3A DSP FPGA. FPGA optimised for
DSP operations or MicroBlazeTM processor
designs.
Flash Memory
Two 128 Mbit SPI Flash Memories. First one is used for
configuration but has spare space for microprocessor code etc.. Device 2 is
totally independent and free to use.
DDR2 Memory
128MByte (option 256MByte) of DDR2 SDRAM configured as one bank 32
bit wide.
PCI104 Interface
32 bit, 33 MHz, 3.3/5V PC104+ interface (PCI) capable of being used
for other bus standards or as 5V tolerant general I/O. There are 66 I/O
available when used as general I/O.
PC104 Interface
8bit or 16bit ISA style bus supported. Capable of being used as
other bus standards or as 5V tolerant general I/O. There 90 I/O
available when used as general I/O.
RS232 Interface
One RS232 interface on board. Baud rates up to 250 Kbit/s. 400
Kbit/s special build option available for OEM batch purchases. The
interface supports 5 outputs and 3 inputs at RS232 levels. This can be
used as a single port or as multiple ports.
RS485 Interface
Four RS485 bidirectional channels on board. Baud rates 10 Mbit/s
per channel as standard. 32 Mbit/s special build option available for
OEM batch purchases.
SATA Hard Disk Interface
Two SATA channels on board provided by SIL3512 controller.
Controller accessed via internal PCI bus off FPGA.
Ethernet Interface
IntelTM 82551 combined
MAC/PHY supporting 10/100T interface. Accessed via internal PCI bus off
FPGA.
USB Host Interface
NXPTM ISP1160 USB
Controller supporting USB 2.0 interface. Accessed via internal PCI bus
off FPGA.
PS2 Interface
Two PS2 interfaces to support mouse and keyboard. If not used for
PS2 eight 5V tolerant signals are available. Four of these signals have
pullups to 5V to facilitate interfacing to 5V CMOS logic devices.
EEprom Memory
One 16 Kbit EEprom Memory.
Real Time Clock
DS1306 real time clock chip on board. Battery holder on board to
support un-powered time keeping and data storage..
DIP Switches
Two 4 bit DIP switches available as inputs to the FPGA.
ZIF Expansion
ZIF socket to support ancillary items like keypads and displays. Supports 3 inputs and one bidirectional I/O. 5V, 3.3V and DGND (0V) are also available on the connector.
LEDs
Power and Ethernet port LEDs.
Oscillator
Fitted with 32MHz MHz 3.3V oscillator. Where possible we will be fitting a MEMS oscillator that is vibration tolerant for those difficult environments.
Clock Generator
Cypress Semiconductor CY22394 clock generator on board supporting multiple clock generation. Controlled by a SPI interface this offers a highly flexible clock source.
Power + Power Jack
Hollybush2 has a 2.1mm Power Jack. This allows the board to operate from a single 5V input. A on-board regulator can deliver up to 6 amps for use on board or to power ancillary plug in cards. The board can also take, or feed, a single 5V or dual 5V/3V from PC104 and PCI104 connectors to power the board or to feed power to other boards.
Hollybush2 offers high performance processor and DSP capability with a significantly better power envelope than competing products. Capabile of operating at extended temperatures without fans or heatsinks it offers a low mass solution to processing requirements.
Programming Cable
Hollybush2 doe not ship with a programming cable. Our Prog2 and adaptor are available for this board at GBP£15. The adaptor is necessary if you wish to Xilinx or other third party programing cables. The adaptor breaks out our on-board fine pitch connector into two Xilinx standard 2X7 JTAG connectors supporting JTAG and SPI Flash programming.

OEM Boards
Hollybush2 can be supplied either as a raw un-programmed board (development board) or as fixed functionality board. As a un-programmed development board you are responsible for the FPGA internal design. As a fixed functionality board we deliver pre-programmed boards with a FPGA design by Enterpoint. Please ask for a quote for your exact requirements.
Derivative, Turnkey Designs and Licensing
We are happy to offer derivative designs of Hollybush2, or
expansion modules, to customers with special requirements. We can also
license this board, or a derivative, for your own manufacture. Please
ask for a quote if you are interested in these services or products.
