Intel’s Netburst can’t evolve any further and its promised successor is nowhere to be seen. However, the last approach used to solve that ( pipeline the datapath and step up the clock frequency) is now failing to scale. To understand Cell’s radical proposal, we must first take into account the problems affecting that era (late 90s-early 00s).Įvery year, consumers ask for more speed. New design philosophies The Cell Broadband Engine chip. In the end, in 2004, IBM unveiled the Cell Broadband Engine (also known as ‘Cell BE’ or just ‘Cell’). If this didn’t sound extravagant enough, the next chip would also be used on the successor of the PS2. In 2000, months after the PS2’s release, Sony formed an alliance with IBM and Toshiba called ‘STI’ with the sole goal to deliver the next chip that could power the next generation of supercomputers. ![]() Well, it turns out the development of the Playstation 3 predates the Playstation Portable one. So, what new MIPS amalgamate were they going to build for the PlayStation 3? This methodology carried on until 2004 with the release of the Playstation Portable. Sony has a history of grabbing existing low-end designs (cheap MIPS cores) and moulding them to achieve acceptable 3D performance at a reduced cost, a process that involved other companies like LSI (for the PS1’s CPU) and Toshiba (for the PS2’s Emotion Engine). Nintendo recently ditched them for a low-end PowerPC core with IBM as their new supplier while Microsoft, the newcomer in this market, chose Intel and their x86 empire. Designed by Toshiba, with MIPS’ technology, again.Īlmost ten years after the introduction of the original MIPS-powered Playstation, we find ourselves in the early noughties, and things are not looking good for SGI/MIPS. Designed by LSI and Sony, using MIPS’ technology. The state of progress The PS1’s CPU (1994). That way, we’ll be able to decompose the chip from top to bottom in a way that not only you will understand how this chip works, but also get the reasoning behind major design decisions. So, before we step into the internals of the PS3’s CPU, I wrote the following paragraphs to bring some historical context into the article. The PS3’s CPU is massively complex, but it’s also a very fascinating work of engineering that intersects complex needs and unusual solutions, prominent in an era of change and experimentation. Welcome to the most recognisable and innovative part of this console. Please take your time (and breaks if needed) and if at the end you are hungry for more, help yourself at the ‘Sources’ section! If you are interested in every area of the Playstation 3, you are in for the whole journey! Having said that, this writing encompasses ~6 years of research and development carried out by countless engineers, so I don’t expect you to digest it all at once. I’m afraid this article is not the typical ‘lunchtime’ one that I usually write for other consoles in this series. This write-up takes a deep look at Sony, IBM, Toshiba and Nvidia’s joint project, along with its execution and effect on the industry. Meanwhile, their new ‘super processor’, the Cell Broadband Engine, is conceived during a crisis of innovation and will have to keep up as trends for multimedia services evolve. In 2006, Sony unveiled the long-awaited ‘next generation’ video-game console, a shiny (albeit heavy) machine whose underlying hardware architecture continues the teachings of the Emotion Engine, that is, focus on vector processing to achieve power, even at the cost of complexity. The remaining 128 MB NAND Flash and the connectors for the Blu-ray PATA drive, Wifi/BT daughterboard, front panel and MultiCard reader are fitted on the back Motherboard with important parts labelled Diagram Main architecture diagram ![]() Showing COK-001 revision (the first one), taken from my CECHA12 model.
