mein herz so weiss

processor ps3

das isser.
der prozessor der ps3. sony, toshiba und ibm haben das herz der ps3, den cell chip gerade der öffentlichkeit präsentiert.
die wichtigsten dinge:

  • cell hat einen hardwareseitigen schutz vor software hacking, sprich das hacken und kopieren (und alles andere denkbar möglich illegale) von games wird von der hardware erschwert (!)
  • das ding ist verdammt schnell
  • und wird verdammt heiss (sprich muss gut gekühlt werden…)

hier eine kleine zusammenfassung von gamespy:

  • CELL is a breakthrough in architectural design
    featuring 8 Synergistic Processing Units (SPU) with Power-based core, with top clock speeds exceeding 4 GHz (as measured during initial laboratory testing)

  • Cell is OS neutral
    supporting multiple operating systems simultaneously
    Cell is a multi-core chip comprising 8 SPUs and a 64-bit Power processor core capable of massive floating point processing
    Special circuit techniques, rules for modularity and reuse, customized clocking structures and unique power and thermal management concepts were applied to optimize the design

  • CELL Is Multi-Core Architecture
    Contains 8 SPUs each containing a 128 entry 128-bit register file and 256 KB Local Store Contains 64-bit Power Architecture with VMX that is a dual thread SMT design
    views system memory as a 10-way coherent threaded machine 2.5MB of on chip memory (512 KB L2 and 8 * 256 KB)
    234 million transistors
    Prototype die size of 221mm
    Frabricanted with 90nm SOI process technology
    Cell is a modular architecture and floating point calculation capabilities can be adjusted by increasing or reducing the number of SPUs

  • CELL Is a Broadband Architecture
    Compatible with 64b Power Architecture
    SPU is a RISC architecture with SIMD organization and Local Store
    128+ concurrent transactions to memory per processor
    High speed internal element interconnect bus performing at 96B/cycle

  • CELL Is a Real-Time Architecture
    Resource allocation (for bandwidth management)
    Locking caches (via replacement management tables)
    Virtualization support with real-time response characteristics across multiple operating systems running simultaneously

  • CELL Is Security-Enabled Architecture
    SPUs dynamically configurable as secure processors for flexible security programming

  • CELL Is a Confluence of New Technologies
    Virtualization techniques to support conventional and real-time applications
    Autonomic power management features
    Resource management for real-time human-interaction
    Smart memory flow controllers (DMA) to sustain bandwidth
