Nearist greatly accelerates big data searches through a revolutionary new hardware platform specifically engineered to handle the computationally demanding task of performing Nearest Neighbor Search on vector representations of content—enabling your search routines to deliver results several orders of magnitude faster than anything else on the market.
This repository conatains the RTL for the (21) lfe5u-85f-8bg381i on Nearist's VSX board. More information about the VSX board can be found !!!here!!! and can be purchased !!!here!!!
/bin/contains the Xilinx Vivado constraint file for the design. Anything you would like to know about pin mapping or any constraints we put on place/route can be found here./lib/contains the all the preconfigured Xilinx IP blocks used in the design. see !!!Getting Started!!! for more information./rtl/contains the source code of the controller FPGA that connects the host to the various devices on the VSX but primarily the distance calculation engine (DCE).- '/run/' The last folder in the repository is a folder dedicated for the project folders of all the configurations and/or simulations you build
see below diagram for a high level view of the design, for more information go to the !!!VSX Design Introduction!!!.
!!!TODO: Add diagram!!!
To build the design one must have the Xilinx Vivado(!!!link!!!) development environment installed on your PC
when creating a new project the following items are required:
- constraint file
- top module and parallel communication interface
- select common files required for the desired DCE and slot configuration
- the xilinx IP core blocks
for further information about building the design go the !!!Getting Started!!! wiki page
