A new book from the designer of the heart of Sony's PS3 - the Cell processor - reveals how Sony inadvertently worked with Microsoft on games consoles. The book,
The Race for a New Game Machine, details how Sony, working with Toshiba and IBM to produce the powerful processor found itself in bed with arch-gaming rival Microsoft due to business alliances.
Two authors produced the book: Mickie Phipps who worked with David Shippy. The latter was chief architect for the power processing unit for the Cell processor at IBM in Austin, Texas. Prior to this he had worked on the G3 PowerPC.
The Race for a New Game Machine details how Sony, Toshiba and IBM formed the Cell partnership in 2001, each committing several hundred million dollars. It was agreed that IBM would be able to sell the Cell to third-parties. Everybody gathered at IBM's Austin HQ.
Then, in 2002, Microsoft approached its old ally-cum-adversary, IBM, with a view to Big Blue creating a chip for a new game console.
This lead to what could be seen either as a comedy or a tragedy depending on your loyalty. Agreements meant that engineers within the IBM team could not share knowledge with Toshiba or Sony colleagues regarding their Xbox 360 chip design. This lead to work being hidden while simultaneously the Sony Cell was in test just below the room where the Xbox 360 internals were being put through their paces.
According to the
Wall Street Journal, Mr Shippy "felt 'contaminated' as he sat down with the Microsoft engineers, helping them to sketch out their architectural requirements with lessons learned from his earlier work on PlayStation".
While Shippy may have felt that way about a Microsoft chip designed with money from Sony, Microsoft's ahead planning was uncontaminated by amateurism. The chips for both consoles arrived on time at IBM's manufacturing facility... but errors occurred in the first batch leaving Sony hanging. Microsoft had arranged for a third-party facility as back-up. Sony had not.
Xbox 360 went on sale in 2005... PlayStation 3 (due to problems with diodes in its Blu-ray drives as well as Cell delay apparently) arrived a year later.
The full title for the book is:
