 +    \subsection{Hardware acceleration}
 +    ClamAV 0.90 comes with support for Sensory Networks' NodalCore
 +    acceleration technology. Thanks to specialized Security Processing Unit
 +    built into NodalCore C-Series accelerators it is possible to achieve more
 +    performance than is possible by just adding general purpose CPUs.
 +    Additionally, Sensory Networks' CorePAKT technology ensures that compiled
 +    signature databases occupy a memory footprint smaller than any other
 +    competing technology on the market - in many cases by up to 90\%. The
 +    ability to store multiple databases in compressed format whilst still
 +    achieving high throughputs makes NodalCore ideal for applications
 +    demanding high performance on large signature databases such as ClamAV.\\
 +    For more information please visit \url{http://www.clamav.net/nodalcore/}
