Filtering Directory Lookups in CMPs With Write-Through Caches
Lecture Notes in Computer Science, 2011In CMPs, coherence protocols are used to maintain data coherence among the multiple local caches. In this paper, we focus on CMPs using write-through local caches, and a directory-based coherence protocol implemented as a duplicate of the local cache tags.

Filtering Dirty Data in DRAM to Reduce PRAM Writes
2015 IFIP/IEEE International Conference on Very Large Scale Integration (VLSI-SoC), 2015Phase-change RAM (PRAM) is a promising candidate of emerging memory technologies which provides large capacity and low leakage power to compensate for the limitations of DRAM in the hybrid DRAM/PRAM memory subsystem. However, for practical applications of PRAM in the hybrid main memory, we need to reduce write traffics to PRAM in order to overcome the ...

Splog Filtering Based on Writing Consistency
2008 IEEE/WIC/ACM International Conference on Web Intelligence and Intelligent Agent Technology, 2008Splog is the key challenge in the access of blogosphere. Existing splog-filtering methods are restricted to the way for traditional web spam filtering, without considering the characteristics of blogs. Inspired by the observation that fake writers (writers of splogs) have striking higher consistent writing behavior than real writers (writers of ...

Electron beam direct write polymeric optical waveguide filters
Optical Fiber Communication Conference and Exhibit, 2002Waveguide wavelength filter with a first order Bragg diffraction grating was demonstrated in ENR polymer. Electron beam sensitive ENR exhibits many unique properties, and both the waveguide and the gratings were fabricated using a single exposure of electron beam.

Electron beam direct-write tunable polymeric waveguide grating filter
IEEE Photonics Technology Letters, 2003We report a tunable electron beam direct-write polymeric waveguide Bragg grating filter based on a negative tone epoxy, The waveguide filter, with a 5-mm-long first-order grating, exhibits a transmission peak of -27 dB and a 3-dB bandwidth of /spl sim/0.8 nm, and there is an excellent agreement between experimental data and simulation results.

Applications of microstructures fabricated by proton beam writing to electric-micro filters
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2009Abstract Fabrication of high-aspect-ratio microstructures was performed by proton beam writing (PBW) using a microbeam line at Takasaki Ion Accelerators for Advanced Radiation Application (TIARA), JAEA Takasaki, JAPAN. As one of the applications of the high-aspect-ratio structures micro-machined by PBW, we utilized the high-aspect pillars for ...

Writing a FORTH discompiler and using FORTH in digital filters and multichannel analysis
Microprocessors and Microsystems, 1983Abstract An introduction to the way in which FORTH runs on a microcomputer is given. The colon definition is identified as an essential part of the language and examples of its use are given. A program to discompile noncolon definitions is presented. Two examples of the use of FORTH are given; in digital filtering and multichannel analysis.
