Things that work extremely well today ( up to 100x)Problem can be re-codedPredictable non-trivial memory access pattern– Can build scatter-gather lists
Problem can benefit from SIMDFocus on 32b float, or <=32b integer
Examples:– FFTw ( best result about 100GFlops )– Terrain Rendering Engine– Volume rendering
Typical code is double-buffered gather-compute-scatter
Can a compiler based approach, without restructuring code specifically for the SPEs result in a chip-level advantage?– About 3-4x more SPEs in same area or power
– But, have to compiler manage local store
Interesting benchmarks: SpecFP, MediaBench, EEMBC, etc.– New more explicitly parallel benchmarks?
Would you ever use an SPE for a SpecInt-type workload?
Innovative Chip is best high-performance embedded processor of 2005
We chose the Cell BE as the best high-performance embedded processor of 2005 because of its innovative design and future potential....Even if the Cell BE accumulates no more design wins, the PlayStation 3 could drive sales to nearly 100 million units over the likely five-year lifespan of the console. That would make the Cell BE one of the most successful microprocessors in history.
“…Cell could power hundreds of new apps, create a new video-processing industry and fuel a multibillion-dollar build out of tech hardware over ten years.”-- Forbes
“It was originally conceived as the microprocessor to power Sony's [PS3], but it is expected to find a home in lots of other broadband-connected consumer items and in servers too.”-- IEEE Spectrum
Toshiba Announces Cell Chip Set and Cell Reference Set
20 September, 2005
Tokyo--Toshiba Corporation today took major steps toward creating a comprehensive development environment for applications based on the Cell microprocessor with the announcement of a Cell Chip Set consisting of the new microprocessor and key peripheral chips, and a Cell Reference Set development platform. The chip set and the reference set will support development of digital consumer products and communication equipment that draw on the powerful broadband capabilities of the Cell microprocessor. "Software developers and other customers will be eager to make full use of Cell's unsurpassed multitasking and real-time processing functions," said Tomotaka Saito, General Manager of Broadband System LSI Division, Toshiba Corporation Semiconductor Company. "The Cell Chip Set and Reference Set will support them in developing products and applications that reach new levels of performance and excitement." The Cell Chip Set is composed of the Cell processor, a Super Companion Chip—the interface between Cell and external audio/visual input/output equipment—and a power supply system chip optimized to drive the Cell microprocessor. The Cell Reference Set development platform consists of a Cell microprocessor, peripheral chips mounted on a printed circuit board with a general-use interface, peripheral equipment, such as DVD and HDD drives, and cooling equipment required for stable operation, all housed in case. The available software includes operating systems and middleware and software development tools. This combination of hardware and software reduces development costs, cuts turnaround time and simplifies testing. Toshiba expects to start marketing the chips set and reference set in April 2006 or later, once it has assured supply of the component chips and all related documentation. Toshiba Corporation will showcase the Cell Chip Set and Cell Reference Set, and demonstrate digital media applications on the Cell Reference Set at the Toshiba booth of CEATEC JAPAN 2005, from October 4 to October 8 at Makuhari Messe. Outlines of Cell Chip Set and Cell Reference Set: Cell Chip Set: Cell microprocessor: Next generation microprocessor jointly developed by IBM, Sony Group and Toshiba. Adopts a multi-core architecture and offers super high-speed data transfer capability. The processor is expected to find application in equipment handling data-rich media applications. Super Companion Chip: Cell's peripheral LSI, which houses audio and image interfaces supporting Cell's super high-speed data transfer capability. The chip also supports a group of interfaces for various systems (video, audio input/output, digital AV interface, IEEE1394, digital tuner interface) and a group of interfaces that make it easier to connect standard input/output devices (standard bus interface, high speed network interface and storage device interface.) Highly efficient power supply system: The supply system is optimized to drive the Cell processor. Includes controller LSI, TB6814FLG, which makes it possible to offer high-speed response and high-accuracy required by Cell. Includes multi-chip module, TB7003FL, which embeds power device in a small 8mm x 8mm package. Realizes small, high-power and high-efficient power supply system which has 4 phases of 1MHz high-speed switches. Cell Reference Set:
Development platform for Cell-based, next generation digital consumer products, High-speed multi-bit wiring technology and wide variety of interfaces that supports broadband system architecture Linux and ITRON are both provided on the hypervisor OS that manages hardware resources. This approach facilitates the reuse of application property. A comprehensive development environment including the Eclipse framework based editor, compiler, debugger, and performance monitor. An audio-visual application model includes simultaneous multiple digital and analog broadcast television reception, recording and playback.
