�Vector Calculator

The Vector Calculator is a fully functional example application of the RARE

project. Its hardware modules are designed for floating point operations

and optimized for speed. Each hardware modules runs at 50 MHz

For comparison purposes, the calculator is implemented in C++, Java and

FPGA hardware and can be executed on a local machine or at a remote machine.

Device utilization for hardware modules are Adder/Subtractor 451

(28%) and Multiplier/Divider� 969 (60%). Each module is highly

pipelined and can handle one or more vector sets at a time.

�PNN Image Classifier

The PNN Image Classifier is another example application developed under

the RARE project. The Classifier is implemented using fixed point modules.�

The hardware design is divided into two sections and each section is mapped

onto an FPGA chip. Device utilizations are 659 (41%) and 928 (58%).

In this application, the host first initializes the board by storing weights values

into the PE1�memory. Then, the host sends input data to the hardware one pixel

at a time through FIFO1. The hardware then calculates the class values for each

class. After that the host receives these values and determines the winning class.
