A number of new and potentially concepts and products based on the concept of security network intelligence have been introduced, including smart flows, intelligent routing, and intelligent web switching. Many intelligent systems focus on a specific security service, function, or device, and do not provide true end-to-end service network intelligence. True security network intelligence requires more than a set of disconnected elements, it requires an interconnecting and functionally coupled architecture that enables the various functional levels to interact and communicate with each other. The article describes information network and CATV applications, backbone network structure. Cable is a natural network for carrying high-capacity, bandwidth-intense information. In the age of analogue program signals, cable's capacity was a natural transmission media for broadcast colour TV and high-fidelity stereo sound programs. In the new digital program signal age, cable's high capacity is a natural network for carrying interactive computer-based, data-intensive multimedia programs.","PeriodicalId":444571,"journal":{"name":"Proceedings.

The 12-bit pipeline ADC is operated at 400 MHz and generates total noise power of 3.38/spl times/10/sup -12//spl middot//spl Delta/f (V/sup 2/) at this frequency. The developed model provides a good estimation of the noise generated by the circuit and gives an accurate prediction on the circuit noise performance.

This BIST scheme employs number theoretic transform to obtain the spectrum of the control sequences (generated by the processor control unit, the Finite State Machine) of the instructions during execution to detect stuck-at and transient faults and weak logic signals. The scheme involves four level logic to detect weak-0 and weak-1 logic signals. Weak signals lead to degradation of the noise margin, particularly in DSM technology based multi-GHz processors. This novel concept is verified by simulation using FSM benchmark circuits. The four level logic has been successfully simulated in Spice, and the results have been presented. Near 100% fault coverage has been achieved. The overall functioning of this test scheme to detect transient faults and signal integrity faults is also shown.","PeriodicalId":444571,"journal":{"name":"Proceedings. DELTA 2004.

Since quiescent supply current flows into the circuits without faults, they can not be tested by a conventional IDDQ test method. We proposed a quiescent supply current test method which is applicable for the bipolar circuit tests, and examined the testability of open faults under an ideal assumption that there are not any process variations. Actually, there are some variations in the quiescent supply current of each gate in implemented logic circuits. Thus, It is necessary to examine the practical testability of the test method before applying to production tests of bipolar logic ICs. In this paper, the practical testability obtained under an assumption that there are some unit-to-unit variations of supply current among gates is examined for ISCAS-85 benchmark circuits. The experimental results show that larger fault coverage can be obtained with a smaller number of test input vectors by our supply current test method than the functional test one based on stuck-at fault models.","PeriodicalId":444571,"journal":{"name":"Proceedings.

In the scheme, an efficient double auto-correlation method based on short training symbols is used for timing synchronization. The performance of the proposed method is comparable or even superior to that of the conventional timing synchronization method under multipath fading channels. By averaging the correlation over four short training symbols, the accuracy of frequency synchronization using short training symbols can be improved to a level that the fine frequency synchronization process using long training symbols in the conventional scheme would not be needed. Thus both timing and frequency synchronization can be achieved using short training symbols alone to reduce computational complexity and overhead. Furthermore, the hardware architecture of the proposed synchronization scheme is developed. The synchronizer is mainly made up of correlator, angle calculator and peak detector, which are implemented by an iterative process, a CORDIC circuit and a finite state machine, respectively. Such an architecture results in low implementation complexity and low computational latency.","PeriodicalId":444571,"journal":{"name":"Proceedings. DELTA 2004.

In this paper we present an enhanced power aware fault tolerant pipelined architecture-xIDAC/E. In our earlier work-IDAC/E, compression and encoding were done on individual instructions whereas xIDAC/E operates on grouped instruction partitions. This offers higher compression efficiency due to repeatability and power reduction due to lesser memory accesses. Simulation results are provided with regard to instruction partitioning, their compression & encoding, and memory re-fetches. Analysis show this power reduction overcompensate the overheads due to partitioning, compression and encoding. The impact of encoding of address & data bus on fault tolerance and power is also provided.","PeriodicalId":444571,"journal":{"name":"Proceedings. DELTA 2004.
