Motivation
• Rising power needs are limiting the increases in speed.
• Transistors can no long handle the heat generated by the power demands.
• Intel and AMD have already introduced dual-core processor.
Context
• Multiprocessors are the way of the future• The Cell is a unique approach
– Nine cores.– 1 Power Processing Unit (PPU)– 8 Synergistic Processing Units (SPU)– Elements connected together by the Internal
Element Interconnect Bus (EIB)
PPU
• Dual-threaded 64-Bit Power PC core.
• L2 512kb Cache.
• Direct access to system memory.
• Responsible for running the OS and coordination of the SPUs.
SPUs
• Synergistic Processing Units
• 256kb of local store, no cache.
• Access to system memory must be handled through DMA via the Memory Flow Controller (MFC).
CELL Architecture Overview
CELL Simulator
• IBM produced a program which simulates the CELL processor.
• Runs on RedHat Fedora.
• It’s FREE.
• Language – C

FFTs on the CELL
• The CELL environment offers up the potential for strong use of parallelization.
• FFTs have the potential to take advantage of this attribute if the algorithm is modified correctly.
