"It has been confirmed that IBM will be pulling out of Cell development, with their current PowerXCell 8i to be the company's last entrance in the technology.
The Cell Processor was originally the brain child of 'The Father of PlayStation' Ken Kutaragi. It was later co-developed by Sony, IBM and Toshiba; making it's way into the PlayStation 3, TV's and super computers.
Featuring a central general-purpose processor, the Cell includes a number of co-processing units with internal memory, known as SPUs. Greatly increasing performance, the Cell's SPUs have been notoriously difficult to develop for, with a number of developers, such as Naughty Dog, making significant breakthroughs of late.
IBM's most recent development in the Cell Processor's design is the PoweXCell 8i, which is featured in the second most powerful supercomputer in the world; Roadrunner.
However, this is where Cell will end for IBM."
