Cell Broadband Engine Hardware Initialization Guide This document describes the sequences for initializing a Cell Broadband Engine processor, from Power-On Reset (POR) through calibration of the memory and I/O interfaces and the PowerPC Processor Element (PPE) firmware. Cell Broadband Engine Linux Reference Implementation Application Binary Interface Specification This document defines a standard interface that allows compiled objects to be linked and run on the Linux Reference Implementation for the Cell Broadband Engine without recompilation or recoding. Cell Broadband Engine Registers This document describes the CBE memory-mapped I/O registers used by the PowerPC Processor Element (PPE), the Synergistic Processor Elements (SPEs) and other units.

20. Standards and Documentation at developerWorks http://www-128.ibm.com/developerworks/power/cell/downloads_doc.html Cell Broadband Engine Architecture V1.0 Like the Power Architecture, but different -- the CBE Architecture builds upon knowledge contained in the Power Architecture "books" and describes the app-level User Mode Environment (UME) and the OS-level Privileged Mode Environment (PME) in astonishingly rich detail. Synergistic Processor Unit (SPU) Instruction Set Architecture V1.0 Somewhere between a general-purpose processor and special-purpose hardware lies the Cell SPU: designed to provide leadership performance in game, media, and broadband applications, this document describes the Instruction Set of the Synergistic Processor Unit (SPU). Get to know all of its instructions. SPU Application Binary Interface Specification V1.4 Including register usage and calling conventions, data type sizes and alignment, low-level system and language binding information, information on loading and linking, and coding examples, this specification defines the system interface for SPU-targeted object files to help ensure maximum binary portability across implementations. SPU Assembly Language Specification V1.3 Program directly to the SPU Instruction Set! This specification will prove an indispensable aid in your efforts as it takes you on a carefully-worded journey describing SPU assembly-level syntax and machine-dependent features for the GNU assembler (but serves as an example specification for other SPU assemblers as well).

21. Standards and Documentation at developerWorks http://www-128.ibm.com/developerworks/power/cell/downloads_doc.html SPU C/C++ Language Extensions V2.1 Unleash the full processing power of the SPUs. This specification extends the C and C++ languages with a rich set of vector data types, several programmer directives, and an extensive set of vector intrinsics. PowerPC Architecture Book, Version 2.01 This three-volume set (pdf), Version 2.01, defines the instruction and registers used by application programs, the storage models, privileged facilities, and related instructions for the POWER4 and POWER4+ processors. PowerPC Architecture Book, Version 2.02 This three-volume set (pdf), Version 2.02, defines the instruction and registers used by application programs, the storage models, privileged facilities, and related instructions for the IBM POWER5 processor family.

The associated assembler and linker additionally support the SPU Assembly Language Specification V1.3. The assembler and linker are common to both the GCC and XL C compilers. Linux Kernel Patch T his set of patches to the Linux operating system provides services needed to support the hardware facilities of the Cell Broadband Engine microprocessor. Fedora Core 5 links SPE Management Library Contains an SPE thread programming model for CBEA applications.
