Book excerpt: Concurrent error detection (CED) is the detection of errors or faults in a circuit or data path concurrent with normal operation of that circuit. The general approach for CED is to calculate a check symbol for the inputs to the circuit under operation, predict the check symbol that will result for the output of the circuit for those inputs, and compare the predicted check symbol to the one that is actually calculated for the output. If the predicted and actual check symbols are different, an error or fault has been detected. The alternative to this check symbol prediction is to use a second copy of the circuit under operation and compare the results of the two circuits. For some classes of circuits the prediction of the output check symbol can require less circuitry than a second copy of the circuit being tested. Four examples of these types of circuits are examined in this dissertation: Arithmetic Logic Units (ALUs), array multipliers, self-synchronous scrambler-descrambler pairs with their intervening data path, and switch fabrics. Faults in integrated circuits tend to produce unidirectional errors. Unidirectional errors are those in which all of the errors are in the same direction (e.g., 0 to 1 errors) within the block of data covered by a given check symbol. For this reason, codes that are optimized for unidirectional errors are the focus of investigation for most of the applications. In particular, the Bose-Lin codes are examined for those applications where unidirectional errors are expected to be typical. In order to examine the performance of the Bose-Lin codes in one of these applications, it was necessary to determine the theoretical performance for Bose- Lin codes for error rates beyond what had been previously studied. This analysis of Bose-Lin codes with large numbers of "burst" errors also included a further generalization of the codes.

Available in PDF, EPUB and Kindle. Book excerpt: Computers are everywhere around us. We, for example, as air passengers, car drivers, laptop users with Internet connection, cell phone owners, hospital patients, inhabitants in the vicinity of a nuclear power station, students in a digital library or customers in a supermarket are dependent on their correct operation. Computers are incredibly fast, inexpensive and equipped with almost unimag- able large storage capacity. Up to 100 million transistors per chip are quite common today - a single transistor for each citizen of a large capital city in the world can be 2 easily accommodated on an ordinary chip. The size of such a chip is less than 1 cm . This is a fantastic achievement for an unbelievably low price. However, the very small and rapidly decreasing dimensions of the transistors and their connections over the years are also the reason for growing problems with reliability that will dramatically increase for the nano-technologies in the near future. Can we always trust computers? Are computers always reliable? Are chips suf- ciently tested with respect to all possible permanent faults if we buy them at a low price or have errors due to undetected permanent faults to be discovered by c- current checking? Besides permanent faults, many temporary or transient faults are also to be expected.

This book was released on 1990 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accordingly, the data block capture and analysis monitoring process is concerned with detecting deviations from the normal performance of the system, known as errors, which are symptomatic of fault conditions. The process consists of repeatedly recording a fixed amount of data from a set of predetermined observation lines of the system being monitored (i.e., capturing a block of data), and then analyzing the captured block in an attempt to determine whether the system is functioning correctly.
