Re: [partial-reconfig] FPGA Multitasking

["Heng Tan" <tanheng78@xxxxxxxxx>]

Thank you for point that out.
The aforementioned paragraph has been revised to the following for
both online and in-print (proof copy modification):

"Currently multiple vendors offer devices with various partial
reconfiguration abilities including Altera, Atmel, Lattice, and
Xilinx.  The partial reconfiguration capability from Altera includes
certain components such as the divider of the its Phase Locked Loop
[41]. The AT40K family from Atmel demonstrates some general partial
reconfiguration performance with literature describing a 50K maximum
gate-equivalent capacity [42]. In this paper, Xilinx FPGAs, which
provide multi-million gate-equivalent capacity and partial
reconfiguration support, are selected to design and prototype our
architecture. They are one of the widely used commercial devices for
partial reconfiguration. At the same time, due to the intrinsic
advantage of MRRA's layered design, the approach can be more readily
ported to other vendor's platforms whenever the fundamental hardware
requirements for partial reconfiguration are met."

Additionally, we reference in other publications the STARS project
which uses partial reconfiguration on ORCA devices.
