Abstract :
The implementation of a first-generation CELL processor that supports multiple operating systems including Linux consists of a 64 bit power processor element (PPE) and its L2 cache, multiple synergistic processor elements (SPE) (B. Flachs et al.) each with its own local memory (LS) (T. Asano et al.), a high bandwidth internal element interconnect bus (EIB), two configurable non-coherent I/O interfaces, a memory interface controller (MIC), and a pervasive unit that supports extensive test, monitoring, and debug functions. In conclusion, special circuit techniques, rules for modularity and reuse, customized clocking structures, and unique power and thermal management concepts were applied to optimize the design.
