The MUltiple SIgnal Classification (MUSIC) algorithm is a powerful technique for determining the Direction Of Arrival (DOA) of signals impinging on an antenna array. The algorithm is serial based, mathematically intensive and requires substantial computing power to realize in real-time. Recently, multi-core processors are becoming more prevalent and affordable. The challenge of adapting existing serial based algorithms to parallel based algorithms suitable for today's multi-core processors is daunting. DOA algorithm has been implemented on Multicore (Intel Nehalem Quad Core), NVIDIA's GPU GeForce GTX 260 and IBM cell broadband engine processor.
