Reconfigurability and reliability of systolic/wavefront arrays by Edwin Hsing-Mean Sha( Book )

1 edition published in 1990 in English and held by 3 WorldCat member libraries worldwide

Abstract: "In this paper we study fault-tolerant redundant structures for maintaining reliable arrays. In particular we assume the desired array (application graph) is embedded in a certain class of regular, bounded-degree graphs called dynamic graphs. We define the degree of reconfigurability DR, and DR with distance DR[superscript d], of a redundant graph. When DR (respectively DR[superscript d]) is independent of the size of the application graph, we say the graph is finitely reconfigurable, FR (resp. locally reconfigurable, LR)
Reliable reconfigurable structures for array architectures by Edwin Hsing-Mean Sha( Book )

1 edition published in 1991 in English and held by 3 WorldCat member libraries worldwide

Abstract: "This paper describes some explicit constructions for reconfigurable array architectures. Given a working architecture (application graph), we add redundant hardware to increase reliability. The degree of reconfigurability, DR, of a redundant graph is a measure of the cost of reconfiguration after failures. When DR is independent of the size of the application graph, we say the graph is finitely reconfigurable, FR. We present a class of simple layered graphs with a logarithmic number of redundant edges, which can maintain both finite reconfigurability and a fixed level of reliability for a wide class of application graphs
Error detection in arrays via dependency graphs by Edwin Hsing-Mean Sha( Book )

1 edition published in 1991 in English and held by 2 WorldCat member libraries worldwide

Abstract: "This paper describes a methodology based on dependency graphs for doing concurrent run-time error detecton in systolic arrays and wavefront processors. It combines the projection method of deriving systolic arrays from dependency graphs with the idea of input- triggered testing. We call the method ITRED, for Input-driven Time- Redundancy Error Detection. Tests are triggered by inserting special symbols in the input, and so the approach gives the user flexibility in trading off throughput for error coverage. Correctness of timing is proved at the dependency graph level. The method requires no extra PE's and little extra hardware
