Linux Enriched Design In Third Generation Wireless Open Access Research Platform

This paper describes embedded Linux system implementation on third generation Wireless Open Access Research Platform (WARP v3). The purpose of this implementation is to integrate operating system (OS) with radio communication system to accomplish flexible and stand-alone communication node for testing different wireless communication protocols. Achieved Linux Enriched WARP v3 (LE-WARP v3) design is a dual (micro-processing) core implementation on field-programmable gate array (FPGA) with Linux running on one core, medium access control (MAC) implemented on other core directly interfacing radio peripherals. Inter-processor communication between both cores is implemented. Hence, achieved result is a versatile system which allows altering any layer of communication network stack, making it practical to test algorithms and prove concept solutions in real-time environment.
