“…Table 4 and Figure 3 projects the Comparison of Compression ratios of proposed method with other test independent Compression techniques, such as the Golomb [3], FDR [4], ALT-FDR [14], EFDR [5], AVR [2], MAVR [22]. It shows that proposed method yields the best Compression ratio compared to other codes.…”

“…The group prefix suggests the group to which the run length of either 0"s or 1"s, belong, while the tail further points out to the specific member of the group. The highlight of this technique holds in the simplicity of the coding table, wherein two group prefix are included in each group, the second prefix being the inverted data of 1 st prefix in each group [2]. The first prefix has m 0s ending with 1.…”

“…Power dissipation during a test is also a significant problem, as the size and complexity of system-on-a-chip (SoC) continues to grow [1]. The power dissipation can increase by a factor of 2-3 compared with the functional mode of operation [2]. The Dynamic power dissipation plays a major role in overall test scan power.…”

“…There are many techniques to control the volume of test data, test application time and power consumption in test mode. Test data volume and power reduction can be achieved by utilizing Built-in-Self-test (BIST) [2,3], test data compaction or test data compression techniques [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][20][21][22]. However, BIST requires a longer test application time.…”

In this paper, run length encoding scheme have been applied on the speech signals of different languages to observe the effect on them. First of all, the speech signals from IPA data base in the category of American-English, German and Japanese of Conventions have taken into account on which this algorithmic scheme is applied. At the encoder end, the speech signal is compressed by this scheme to observe the effect. Further, the speech signal is reconstructed at the decoder end from the compressed speech signal. The hearing quality of the reconstructed speech signal is observed to be the same as the RLE technique is a loss less compression technique. Finally, a comparison of computed CRs of three languages is produced which reflects the relative performance of this encoding algorithmic scheme.

Today's electronic systems, with ever-growing demand for mobile computing devices, are more complex, fast and energy efficient. Cost and quality are the major issues in testing these circuits. The test data storage requirements, along with the operating frequency and channel capacity, have a significant impact on the test cost. This paper presents a new compression scheme based on Alternating Variable Run-length (AVR) codes for reducing the test data. Weighted transition based reordering scheme is adopted prior to the compression scheme to improve the compression ratio (CR). By applying an appropriate mapping scheme, sufficient reduction in power has been achieved. The scheme is also found to have a maximum of 10% increase in compression ratio when compared to the conventional frequency directed run-length codes (FDR) codes and extended FDR (EFDR) codes without any significant on-chip area overhead. The experiments are performed on ISCAS'89 benchmark circuits.
