Book Recovery Act CAREER

Download or read book Recovery Act CAREER written by and published by . This book was released on 2014 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research goal of this CAREER proposal is to develop energy-efficient, VLSI interconnect circuits and systems that will facilitate future massively-parallel, high-performance computing. Extreme-scale computing will exhibit massive parallelism on multiple vertical levels, from thou sands of computational units on a single processor to thousands of processors in a single data center. Unfortunately, the energy required to communicate between these units at every level (on chip, off-chip, off-rack) will be the critical limitation to energy efficiency. Therefore, the PI's career goal is to become a leading researcher in the design of energy-efficient VLSI interconnect for future computing systems.

Book Area and Energy Efficient VLSI Architectures for Low density Parity check Decoders Using an On the fly Computation

Download or read book Area and Energy Efficient VLSI Architectures for Low density Parity check Decoders Using an On the fly Computation written by Kiran Kumar Gunnam and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The VLSI implementation complexity of a low density parity check (LDPC) decoder is largely influenced by the interconnect and the storage requirements. This dissertation presents the decoder architectures for regular and irregular LDPC codes that provide substantial gains over existing academic and commercial implementations. Several structured properties of LDPC codes and decoding algorithms are observed and are used to construct hardware implementation with reduced processing complexity. The proposed architectures utilize an on-the-fly computation paradigm which permits scheduling of the computations in a way that the memory requirements and re-computations are reduced. Using this paradigm, the run-time configurable and multi-rate VLSI architectures for the rate compatible array LDPC codes and irregular block LDPC codes are designed. Rate compatible array codes are considered for DSL applications. Irregular block LDPC codes are proposed for IEEE 802.16e, IEEE 802.11n, and IEEE 802.20. When compared with a recent implementation of an 802.11n LDPC decoder, the proposed decoder reduces the logic complexity by 6.45x and memory complexity by 2x for a given data throughput. When compared to the latest reported multi-rate decoders, this decoder design has an area efficiency of around 5.5x and energy efficiency of 2.6x for a given data throughput. The numbers are normalized for a 180nm CMOS process. Properly designed array codes have low error floors and meet the requirements of magnetic channel and other applications which need several Gbps of data throughput. A high throughput and fixed code architecture for array LDPC codes has been designed. No modification to the code is performed as this can result in high error floors. This parallel decoder architecture has no routing congestion and is scalable for longer block lengths. When compared to the latest fixed code parallel decoders in the literature, this design has an area efficiency of around 36x and an energy efficiency of 3x for a given data throughput. Again, the numbers are normalized for a 180nm CMOS process. In summary, the design and analysis details of the proposed architectures are described in this dissertation. The results from the extensive simulation and VHDL verification on FPGA and ASIC design platforms are also presented.

Book Efficient VLSI Divide and Conquer Array Architectures for Multiplication

Download or read book Efficient VLSI Divide and Conquer Array Architectures for Multiplication written by and published by . This book was released on 2007 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we introduce an efficient VLSI array architecture for binary multiplication, and discuss its extension for vector-scalar multiplication. The architectures are based on an existing parameterized divide and conquer algorithm that uses optimal partitioning and redundancy removal for simultaneous computation of partial sums. Four versions of the proposed Parameterized Binary Multiplier Architecture (PBMA), two for the general case where the multiplicand and the multiplier are variables (PBMA-A and PBMA-AT) and two for the special case where the multiplier is programmable constant (cPBMA-A and cPBMA-AT), are implemented and compared to the conventional Carry-Save Array Multiplier implementation. PBMA-A is optimized for area (A) and is shown to achieve significant area (A) savings at the cost of increased operational delay (T), while PBMA-AT is optimized for area-time product (AT) and is shown to achieve significant area-time product (AT) savings and a smaller operational delay (T) at the cost of smaller area (A) savings. cPBMA-A is optimized for area (A) and is shown to achieve significant area (A) savings without any major impact on operational delay (T), while cPBMA-AT is optimized for area-time product (AT) and is shown to achieve significant area-time product (AT) savings and a significantly smaller operational delay (T) at the cost of slightly smaller area (A) savings. All versions are also shown to be highly power (P) efficient. Four versions of the proposed Parameterized Vector-Scalar Multiplier Architecture (PVSMA), two for the general case where the vector and the scalar are variables (PVSMA-A and PVSMA-AT) and two for the special case where the scalar is programmable constant (cPVSMA-A and cPVSMA-AT), are implemented and compared to the conventional parallel implementation with Carry-Save Array Multipliers. PVSMA-A is optimized for area (A) and is shown to achieve significant area (A) savings at the cost of increased operational delay (T), while PVSMA-AT is optimized for area-time product (AT) and is shown to achieve significant area-time product (AT) savings and a smaller operational delay (T) at the cost of smaller area (A) savings. cPVSMA-A is optimized for area (A) and is shown to achieve significant area (A) savings without any major impact on operational delay (T), while cPVSMA-AT is optimized for area-time product (AT) and is shown to achieve significant area-time product (AT) savings and a significantly smaller operational delay (T) at the cost of slightly smaller area (A) savings. All versions are also shown to be highly power (P) efficient.

Book Efficient VLSI Very Large Scale Integration Fault Simulation

Download or read book Efficient VLSI Very Large Scale Integration Fault Simulation written by J. H. Reif and published by . This book was released on 1985 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Let C be an acyclic boolean circuit with n gates and equal to or less than n inputs. A circuit manufacture error may result in a Stuck-at (S-A) fault is a circuit identical to C except a gate v only outputs a fixed boolean value. The (S-A) fault simulation problem for C is to determine all possible S-A faults which can be detected (i.e., faults for which a faulty circuit and C would give distinct outputs) by a given test pattern input. We consider the case where C is a tree (i.e., has fan-out 1). We give practical algorithm for fault simulation which simultaneously determines all detectable S-A faults for every gate in the circuit tree C. Our algorithm requires only the evaluation of a circuit FS(C) which has equal to or less than 3(d+1), when d is the depth of C. Thus the sequential time of our algorithm is equal to or less than 7n, and the parallel time is equal to or less than 3(d+1). Furthermore FS(C) requires only a small constant factor more VLSI area than does the original circuit C. We also extend our results to get efficient methods for fault simulation of oblivious VLSI circuits with feedback lines. Originator supplied keywords include: VLSI; fault simulation; stuck-at faults; reliable computation; boolean functions; partial derivations; and boolean circuits.

Book Principles of VLSI System Planning

Download or read book Principles of VLSI System Planning written by Allen M. Dewey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a new type of computer aided VLSI design tool, called a VLSI System Planning, that is meant to aid designers dur ing the early, or conceptual, state of design. During this stage of design, the objective is to define a general design plan, or approach, that is likely to result in an efficient implementation satisfying the initial specifications, or to determine that the initial specifications are not realizable. A design plan is a collection of high level design decisions. As an example, the conceptual design of digital filters involves choosing the type of algorithm to implement (e. g. , finite impulse response or infinite impulse response), the type of polyno mial approximation (e. g. , Equiripple or Chebyshev), the fabrication technology (e. g. , CMOS or BiCMOS), and so on. Once a particu lar design plan is chosen, the detailed design phase can begin. It is during this phase that various synthesis, simulation, layout, and test activities occur to refine the conceptual design, gradually filling more detail until the design is finally realized. The principal advantage of VLSI System Planning is that the increasingly expensive resources of the detailed design process are more efficiently managed. Costly redesigns are minimized because the detailed design process is guided by a more credible, consistent, and correct design plan.
