Cell Broadband Engine Architecture from 20,000 feet
New article at IBM developerWorks:
The Cell Broadband Engine Architecture (CBEA, or, informally, "Cell") defines a new processor structure based upon the 64-bit Power Architecture™ technology, but with unique features directed toward distributed processing and media-rich applications. The Cell architecture defines a single-chip multiprocessor consisting of one or more Power Processor Elements (PPEs) and multiple high-performance SIMD Synergistic Processor Elements (SPEs). While each SPE is an independent processor running its own application programs, a shared, coherent memory and a rich set of DMA commands provide for seamless and efficient communications between all Cell processing elements. This article provides a concise view inside the Cell's architecture.
