This paper presents a Data Width-aware Register file Protection (DWRP) technique to cope with Multiple Bit Upsets (MBUs) occurring in the register file of embedded processors. The DWRP technique has been proposed based on the fact that there are often a significant number of bits in the register file, which are not fully occupied by data. The DWRP technique efficiently exploits these available free bits for reliability enhancement purposes. In this regard, every register is equipped with three extra tag bits to specify the amount of available free bits in a register. Then the appropriate parity or hamming code is used based on the information of the tag field to protect the register file... 

Three-dimensional (3D) bundles of self-assembled lanthanum hydroxide nanorods with average crystallite size of about 20 nm were fabricated via a facile and rapid microwave-assisted chemical route. The obtained material was characterized with X-ray diffractometry (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations. The obtained nanorods have average diameter of about 115 nm and average length of about 730 nm. Self-assembly of primary La(OH)3 nanoparticles and their subsequent anisotropic growth along 〈2 0 0〉 direction, was proposed to be the mechanism for the formation of 3D bundles of nanorods, using TEM images. The thermal behavior of the...
