Introduction
• There are some limitations on Reconfigurable platform as
compared to usual microprocessor based system. With the
latest FPGA having more than 10 million gates and by using
dynamic reconfiguration it is now possible to run multiple
applications on a single FPGA. This improvement of
technology in FPGA made it a candidate for operating system
as previously it was not possible because of shortage of
resources over it.
• The concept of operating system for FPGA platform was first
proposed by (Wigley & Kearney 2001). They introduced
ReConfigMe operating system for FPGA boards. It allows
execution of multiple applications simultaneously. Then an
embedded Linux for FPGA was introduced by (William &
Bergmann 2004).

Introduction
• All these developments are having master/slave relationship,
where microprocessor based desktop or PC running Linux,
Unix or Windows acts as a master is connected with single or
multiple FPGA boards which acts as slave. This master/slave
relationship has some bandwidth limitations which does not
allow us to fully utilize this FPGA hardware.
• With the development of soft processor MicroBlaze and built
in FPGA hard board processors there is a need that FPGA
should work as a standalone device without having master
salve relationship or external dependency. This feasibility
study is to check out that whether we can port ReConfigMe
operating system over Petalinux operating system or not?

ReConfigMe
 It is an operating system for reconfigurable computing developed by
UniSA.
 It allows to share FPGA resources dynamically between multiple
executing applications.
 It involves external interface to communicate with FPGA device.
 It is divided into three tiers which are
1. User Tier
Performs the interaction between user and operating system.
2. Operating System Tier
Responsible for allocation and partitioning of applications and
transfer of application data and configuration information
between platform and user tier.
3. Platform Tier
Responsible for communication to and from the reconfigurable
platform.

PetaLinux
 It is an embedded operating system developed by PetaLogix
for FPGA.
 It also requires master / slave communication to work.
 It works on Xilinx FPGA.
Needs physical connection for communication

Benefits of this Study
If we successfully port the ReconfigMe OS over
PetaLinux OS then we will get following benefit

FPGA will be able to work as a standalone device
without having external dependency or
master/slave relationship.

FPGA will be able to run multiple applications
simultaneously.
