Multipliers With Approximate 4–2 Compressors and Error Recovery Modules
Minho Ha,Sunggu Lee +1 more
TL;DR: The proposed design, even with the additional error recovery module, is more accurate, requires less hardware, and consumes less power than previously proposed 4–2 compressor-based approximate multiplier designs.
Journal ArticleDOI
Design and implementation of a private and public key crypto processor and its application to a security system
Howon Kim,Sunggu Lee +1 more
TL;DR: The design and implementation of a crypto processor, a special-purpose microprocessor optimized for the execution of cryptography algorithms, which can be used for various security applications such as storage devices, embedded systems, network routers, security gateways using IPSec and SSL protocol, etc.
Proceedings ArticleDOI
Power management of hybrid DRAM/PRAM-based main memory
TL;DR: In order to reduce DRAM refresh energy which occupies a significant portion of total memory energy, a runtime-adaptive method of DRAM decay is presented and two methods, DRAM bypass and dirty data keeping, are presented for further reduction in refresh energy and memory access latency.
Journal ArticleDOI
Probabilistic diagnosis of multiprocessor systems
Sunggu Lee,Kang G. Shin +1 more
TL;DR: This paper critically surveys methods for the automated probabilistic diagnosis of large multiprocessor systems and produces a chart showing the comparative advantages of the various diagnosis algorithms on the basis of several factors important to the probabilism diagnosis.
Journal ArticleDOI
Interleaved all-to-all reliable broadcast on meshes and hypercubes
Sunggu Lee,Kang G. Shin +1 more
TL;DR: The IHC algorithm with the minimum value of /spl eta/ is shown to be optimal in minimizing the execution time of ATA reliable broadcast when used in a dedicated mode (with no other network traffic).
