2 2 IRAM Overview Low power, high performance processor for multimedia Mixed logic and DRAM –On-chip bandwidth, low power Vector processing –Parallelism replace high clock »200 MHz, 3.2 Gflops, 2 Watts –Simple issue and control logic (power, area) »Push complexity into compiler; well-understood model Compare to SIMD media extensions (MMX, VIS,…) –Multimedia has fine-grained data parallelism. –Scalable, multi-generation instruction set Working with application experts (video and speech)

3 3 ISTORE Overview Two kill applications for future –Storage and retrieval Design points –2000: 80 nodes in 3 racks –2001: 1000 nodes with IBM (?) –2005: 10K nodes in 1 rack (?) »Add IRAM to 1” disk Key problems are availability, maintainability, and evolutionary growth (AME) of a thousand node servers Approach Hardware built for availability: monitor, diagnostics New class of benchmarks for AME Reliable systems from unreliable hw/sw components Introspection: the system watches itself
