Abstract: A heterogeneous memory system is implemented using a low-latency near memory (NM) and a high-latency far memory (FM). Pages in the memory system include NM blocks stored in the NM and FM blocks stored in the FM. A page is assigned to a region in the memory system based on the proportion of NM blocks in the page. When accessing a block, the block address is used to determine a region of the memory system, and a block offset is used to determine whether the block is stored in NM or FM. The memory system may observe memory accesses to determine the access statistics of the page and the block. Based on a page's hotness and access density, the page may be migrated to a different region. Based on a block's hotness, the block may be migrated between NM and FM allocated to the page.

Abstract: A method for operating a printer to print with the operation having a pre-determined period of time between the start of a printing process and the completion of a fuser module heating process is provided. The method includes performing the heating process by heating the fuser module towards a target temperature. Next, compare the rest of the expected period of time for the fuser to arrive at the target temperature with the pre-determined period of time. If the expected period of time is no more than the predetermined period of time, start the printing processes. Lastly fuse the printing medium after the completion of the printing processes. The present invention also includes a method for operating a printer to print with the operation having an adjustable period of time between the start of the printing processes and the completion of a fuser module heating process.

Abstract: An apparatus and method for shifting the image-forming region of a printing device is disclosed. The apparatus includes a photoconductor, an encoder, several rollers, and a controlled device. The present invention is used to shift the image-forming region in the photoconductor by the controlled device. The damage of the image-forming region in the photoconductor can be reduced. The lifetime of the photoconductor can be extended. In addition, the controlled device uses firmware to shift the image-forming region. The shifting method can be a sequential mode or random mode.
