For these reasons, Cell is widely regarded as a challenging environment for software development.
The architecture will not be widely used unless it is adopted by the software development community.
A DMA operation can transfer either a single block area of size up to 16KB, or a list of 2 to 2048 such blocks.
One of the major design decisions in the architecture of Cell is the use of DMAs as a central means of intra-chip data transfer, with a view to enabling maximal asynchrony and concurrency in data processing inside a chip.
Over 400 engineers from the three companies worked together in Austin, with critical support from eleven of IBM's design centers.
During this period, IBM filed many patents pertaining to the Cell architecture, manufacturing process, and software environment.
Bandai Namco Entertainment used the cell processor for their 357 arcade board as well as the subsequent 369.
The architectural design and first implementation were carried out at the STI Design Center in Austin, Texas over a four-year period beginning March 2001 on a budget reported by Sony as approaching US0 million.An early patent version of the Broadband Engine was shown to be a chip package comprising four "Processing Elements", which was the patent's description for what is now known as the Power Processing Element (PPE).Each Processing Element contained 8 APUs, which are now referred to as SPEs on the current Broadband Engine chip.The world's three most energy efficient supercomputers, as represented by the Green500 list, are similarly based on the Power XCell 8i.The 45 nm Cell processor was introduced in concert with Sony's Play Station 3 Slim in August 2009.
