FPGA Performance

- DES > 16 Gbps / 250M Keys / second

- RC4 > 10 Gbps / 12M Keys / second

- > 16 Billion Multiply and Accumulates / second

Typical Applications

- Application on Card (AOC) systems. Vendors

sell their applications packaged with the

platform that they run on.

- Hybrid embedded processor / DSP applications

- Encryption / decryption

- Security algorithms and testing

- Software radio component

- Embedded control systems

- Embedded web servers / applications

- Weight and size constrained environments such

as UAVs, surveillance systems and

environmental monitoring devices.

- Complete development environment for laptop

computers. Ideal for rapid prototyping and

classroom environments.

Analog Capabilities

- 1 High Speed Analog to Digital

- 8 Bit @ 105MS/Sec

- 10 Bit @ 80MS/Sec

- 1 High Speed Digital to Analog

- 8 Bit @ 210MS/Sec

- 10 Bit @ 165MS/Sec

Features

- Complete Cardbus host interface capable of bus

speeds up to 1 Gbps

- DSP capability of the Virtex-4 FPGA

- Bus interface re-configurable to fit other bus nterface

protocols

- Works with Xilinx standard tool set (ISE, EDK, and

Platform SDK)

- Works with Starbridge Systems’ Viva, a graphical

development and modeling tool set designed for

parallel computing and IP portability

- Pico Flash utility for FPGA image and software

executable management. Runs on Windows, Linux,

and Apple Hosts

- Available plug-in for Matlab

- Pico DSP Accelerator / Xilinx System Generator plug-

in for Simulink available

- Available complete board support packages for

PowerPC embedded computing with Xilinx EDK

- Available port of RTCA DO-178B compliant UCOS-II

deterministic / pre-emptive kernel

- Available Linux port

- Available port of Green Hills Integrity RTOS

- Dynamic image swapping: unique design allows for

many FPGA images and user software images to be

stored on the PICO E-14's flash memory at one

time. FPGA and software images are associated

(paired). This allows image sets to be swapped

dynamically. Applications can store data in SDRAM.

This data can then be used by subsequent image

sets seamlessly.
