Abstract :
To enhance security in WLAN, CCMP is introduced in IEEE 802.11i. This paper presents a heterogeneous multi-core architecture based on NoC to support high-speed CCMP application. Four general processors and twelve security ASIPs are connected by a 4×4 mesh NoC. A modified PTLU is implemented in each ASIP to accelerate AES operations. Task parallelism in CCMP is exploited to obtain high throughput. Synthesized in SMIC 0.13μm CMOS technology, the proposed system measures a hardware cost of 3.08M gates. Experiment results show that the system achieves a throughput of 787Mbps at 84MHz.
