Guide to Cell/B.E. Programming Documentation

Guide to Cell Broadband Engine Programming Documentation
Introduction
This Guide is designed to help you navigate the programming documentation for the Cell Broadband Engine™ (Cell/B.E.) processor. The documents areavailable on the public Sony Computer Entertainment website (http://cell.scei.co.jp/e_download.html) and the IBM website (http://www-128.ibm.com/developerworks/power/cell/). The Guide summarizes the documentation, explaining the relevance of each document to particular Cell/B.E. programming roles and objectives. Throughout this Guide and the documentation it summarizes, the Cell/B.E. is variouslyreferred to as the Cell Processor, Cell Broadband Engine™, CBE, Cell BE, or BE. Figure 1, “Cell/B.E. Block Diagram” and Figure 2, “Storage Domains” define the acronyms used in the Cell/B.E. documentation. For a more complete glossary, see the CBE Programming Handbook. Figure 1 Cell/B.E. Block Diagram

Guide to Cell/B.E. Programming Documentation

The PPE (Figure 1 and Figure 2) is a general-purpose, 64-bit PowerPC RISC processor that runs the operating system(s) for all applications and external interfaces on the Cell/B.E. It operates on scalars or vectors containing 8- to 64-bit fixed-point or single- or double-precision floating-point data types. Eachof the eight SPEs (Figure 1 and Figure 2) is a 128-bit RISC processor that executes the SPU instruction set, which is designed for data-rich single-instruction, multiple data (SIMD) and scalar applications. It operates on scalars or vectors containing 8- to 128-bit fixed-point or single- or double-precision floating-point data types. An SPE consists of two main units – the SPU, which executesinstructions, and the MFC, which controls DMA transfers and related functions. In general, the term “SPU” refers to the instruction-execution unit, and the term “SPE” refers to either or both of the SPU and MFC. However, some documents use the terms “SPU” and “SPE” interchangeably.
