Signal processing on platforms with multiple cores: Part 1 - Overview and methodologies [From the Guest Editors]

Multicore processors are now prevalent in all major domains of signal processing. Many laptop and desktop computers today are shipped with dualcore and even quad-core processors. The number of cores is even higher for the Sony PlayStation 3, which is equipped with an 8-core IBM CELL Broadband Engine processor, Nvidia GeForce 9800 GX2, which has 256 stream processors, and SUN UltraSPARC T1/T2 processor, which has 8 cores. Technology predictions indicate that this trend will continue and that the number of cores per processor can easily double around every two or three years.
