A defect tolerant self-organizing nanoscale SIMD architecture

Abstract: The continual decrease in transistor size (through either scaled CMOS or emerging nano-technologies) promises to usher in an era of tera to peta-scale integration. However, this decrease in size is also likely to increase defect densities, contributing to the exponentially increasing cost of top-down lithography. Bottom-up manufacturing techniques, like self-assembly, may provide a viable lower-cost alternative to top-down lithography, but may also be prone to higher defects. Therefore, regardless of fabricati… Show more

“…Figure 3 compares the average latency of PSIs with all instructions among six test programs simulated by a timing-accurate SOSA simulator. The SOSA simulator is an event-driven simulator where each activity in a node is an event and its latency is a multiple of "time quantum" defined as the time taken to perform one part of the internode asynchronous communication handshake [Patwardhan et al 2006c]. The test programs include Add, a software-emulated floating point program for addition and normalization, BinPack, a pipelined version of integer bin-packing with a first-fit heuristic using N PEs for N bins, GauFilter, GenFilter, and MedFilter which are image processing programs that apply a generic 3x3 filter, a separable Gaussian filter, and a median filter to an NxN image using N 2 PEs, respectively, and finally Search, a program that finds a 32-bit input string in a database using O(N ) PEs for N strings.…”
