In a simple analysis, the Cell processor can be split into four components: external input and output structures, the main processor called the Power Processing Element (PPE) (a two-way simultaneous-multithreaded PowerPC 2.02 core), eight fully functional co-processors called the Synergistic Processing Elements, or SPEs, and a specialized high ...
The Power Processing Element (PPE) comprises a Power Processing Unit (PPU) and a 512 KB L2 cache.In most instances the PPU is used in a PPE. The PPU is a 64-bit dual-threaded in-order PowerPC 2.02 microprocessor core designed by IBM for use primarily in the game consoles PlayStation 3 and Xbox 360, but has also found applications in high performance computing in supercomputers such as the ...

Cell is a 64-bit multi-core microprocessor microarchitecture that combines a general-purpose PowerPC core of modest performance with streamlined coprocessing elements which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation. POWER, PowerPC, and Power ISA architectures.
Mar 17, 2005 · The role of the PPE in Cell is to handle the tasks that any general purpose microprocessor would run; basically, anything that you could run on your Athlon 64 would be run on the PPE. The PPE ...

A high-speed bus called the Element Interconnect Bus (EIB) is used for connecting these processor cores within the Cell. The EIB also provides connections to main memory and external I/O devices, making it possible for processor cores to access data. Details of each processor core are described below. 1.2.2 PowerPC Processor Element (PPE)
