Code compression techniques have been used widely in embedded systems to decrease the amount of storage resources needed or to decrease power consumption, and in some cases, to improve performance too. This paper evaluates, using cache models, the performance, power, and cost benefits that code compression can provide in an instruction memory hierarchy. It also compares several important code c...

the transformation of 2D-DCT is applied in video compression technique with 14 additions for area and power compaction. The proposed structure could be implemented in 4, 8, 16, 32 bit size. The proposed 2D-DCT system is used to reduce the complexity of video compression. It results in less area delay and power consumption with “0” and “1” by implementing in FPGA. HEVC/H265 is applied for enhanc...

A wire-array flux-compression cartridge installed on Sandia's Saturn pulsed power generator doubled the current into a 3-nH load to 6 MA and halved its rise time to 100 ns. The current into the load, however, was unexpectedly delayed by almost 1 micros. Estimates of a plasma flow switch acting as a long-conduction-time opening switch are consistent with key features of the power compression. Th...

Video applications in mobile devices call for low complexity video compression algorithms. This paper presents a low complexity 2-power transform for video compression. The elements of the transform matrix are all in 2’s low-order power. The transform computation requires only 28 additions and 10 binary shifts. Computational complexity analysis, coding gains and RD curve comparison show that ou...

Test compression has become a de-facto technique in VLSI testing. Test data volume is a serious concern for the semiconductor testing because it not only prolongs the testing time of the integrated circuits (Ics), but also raises the tester memory depth requirements and excessive capture power at-speed testing has also become a serious concern. So it is important to co-optimize test power and c...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

Energy is an important consideration in the design and deployment of wireless sensor networks (WSNs) since sensor nodes are typically powered by batteries with limited capacity. Since the communication unit on a wireless sensor node is the major power consumer, data compression is one of possible techniques that can help reduce the amount of data exchanged between wireless sensor nodes resultin...

Gas turbine systems with wet compression have a potential for future power generation, since they can offer a high efficiency and a high specific power with a relatively low cost. In this study influence of ambient condition on the performance of the wet compression process is investigated with a non-equilibrium analytical modeling based on droplet evaporation. Transient behaviors of droplet di...
