26 1. INTRODUCTION 1.5 IBM Cell Broadband Engine Architecture 1.5.1 Cell Processor Chip The Cell Broadband Engine Architecture (CBEA) [39] is designed to achieve high computing performance with better area/performance and power/performance ratios than the conventional multi-core architectures. The CBEA defines a heterogeneous multi-processor architecture where general purpose processors called Power Processor Elements (PPE) and SIMD 1 processors called Synergistic Processor Elements (SPE) are connected via a high speed on-chip coherent bus called Element Interconnect Bus (EIB). The CBEA architecture is flexible and the ratio of the different elements can be defined according to the requirements of the different applications. The first implementation of the CBEA is the Cell Broadband Engine (Cell BE or informally Cell) designed for the Sony Playstation 3 game console, and it contains 1 PPE and 8 SPEs. The block diagram of the Cell is shown in Figure 1.12. The PPE is a conventional dual-threaded 64bit PowerPC processor which can run existing operating systems without modification and can control the operation of the SPEs. To simplify processor design and achieve higher clock speed instruction reordering is not supported by the PPE. IT has a 32kB Level 1 (L1) cache memory, which is a set-associative, parity protected, 128 bit sized cache-line memory, and 512kB Level 2 (L2) unified (data and instruction) cache memory. The Power Processing Element contains several functional units, which composes the Power Processing Unit shown in Figure 1.13. The PPU executes the PowerPC Architecture instruction set and the Vector/SIMD Multimedia Extension instructions. The Instruction Unit performs the instruction-fetch, decode, dispatch, issue, branch, and completion portions of execution. It contains the L1 instruction cache. The Load Store Unit performs all data accesses, including execution of load and store instructions. It contains the L1 data cache. The Vector/Scalar Unit includes a Floating-Point Unit (FPU) and a 128-bit Vector/SIMD Multimedia Extension Unit (VXU), which together 1 SIMD - Single Instruction Multiple Data
