An Adaptively Dividable Dual-Port BiTCAM for Virus-Detection Processors in Mobile Devices

Network security is in high demand because of increasing network attacks. As mobile devices have limited CPU power, dedicated hardware is required to provide sufficient virus detection performance with a small energy cost. We present an adaptively dividable dual-port BiTCAM, which unifies binary and ternary CAM, in a virus-detection processor for mobile devices. The BiTCAM design achieves a 48% power-consumption reduction and a 40% transistor-count reduction compared to a design with two separate single-port TCAMs.
