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 2015).If you use accessibility tools, an eBook or legacy browsers, switch to the ‘classic’ edition. In addition, since POLQ is an error-prone DNA polymerase, MMEJ introduces frequent base substitutions (Ceccaldi et al. MMEJ, just like classical NHEJ, can result in genomic translocations (Ghezraoui et al. Similar to single strand annealing (SSA), MMEJ leads to deletion of one of the microhomology regions used for annealing and the DNA sequence in between two annealed microhomology regions. The MRN complex subsequently recruits DNA ligase 3 (LIG3) bound to XRCC1 (LIG3:XRCC1) to ligate the remaining single strand nicks (SSBs) at MMEJ sites (Della-Maria et al.

Using analogy with POLB-mediated long patch base excision repair (BER), it is plausible that PARP1 (or PARP2) dimers coordinate the extension of annealed 3'-ssDNA overhangs via POLQ-mediated strand displacement synthesis with FEN1-mediated cleavage of the resulting 5'-flaps (Liang et al. In a poorly studied sequence of events, POLQ promotes the annealing of two 3'-ssDNA overhangs through microhomologous regions that are optimally 10-19 nucleotides long. Single strand DNA (ssDNA) at resected DNA DSB ends recruits PARP1 or PARP2 homo- or heterodimers, together with DNA polymerase theta (POLQ) and FEN1 5'-flap endonuclease. MMEJ is initiated by a limited resection of DNA DSB ends by the MRN complex (MRE11A:RAD50:NBN) and RBBP8 (CtIP), in the absence of CDK2-mediated RBBP8 phosphorylation and related BRCA1:BARD1 recruitment (Yun and Hiom 2009).

Therefore, MMEJ may be triggered when the amount of DNA double strand breaks (DSBs) overwhelms DNA repair machinery of higher fidelity or when cells are deficient in components of high fidelity DNA repair. Contrary to the classical NHEJ and other HDR pathways, homologous recombination repair (HRR) and single strand annealing (SSA), MMEJ does not require ATM activation. Homology directed repair (HDR) through microhomology-mediated end joining (MMEJ) is an error prone process also known as alternative nonhomologous end joining (alt-NHEJ), although it does not involve proteins that participate in the classical NHEJ.
