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 ...
Cell microprocessor implementations. Cell microprocessors are multi-core processors that use cellular architecture for high performance distributed computing. The first commercial Cell microprocessor, the Cell BE, was designed for the Sony PlayStation 3. IBM designed the PowerXCell 8i for use in the Roadrunner supercomputer.

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)
Although the Cell Broadband Engine derives much of its touted Gigaflops from the 8 (limited to 6 in the PS3) Synergistic Processor Elements (SPEs), the Power Pro-cessing Element (PPE) is the conductor, presiding over the computing orchestra. In this chapter we shall focus solely on the PPE, as we examine its design and archi-
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.
