摘要： A computer system comprising a processor including a display controller operative to output display data and a clock signal, and a programmable logic device communicatively connected to the processor, the programmable logic device including a first FIFO (first in first out) module operative to receive display data from the display controller and output display data to a display device, a second FIFO module, a scaler module communicatively connected to the first FIFO module and the second FIFO module operative to scale the display data received from the first FIFO module and output the scaled display data to the second FIFO module, and a synchronization generator operative to receive the clock signal from the display controller and to control the first FIFO and the second FIFO.

摘要： Embedded devices typically have an operating system, one or more file-systems, as well as a bootloader and other data components resident in flash memory. During software development and testing, there is frequently a need to selectively update a combination of such images. The described technique organizes the images in the flash memory such that one can speed up the update process by eliminating relocation of existing images. A command-driven update mechanism provides a flexible process—eg, one can upload the images back to a host, one can update the update code itself, etc. A start handshake is used that enables auto-detection of the embedded serial port that is used for the update.

摘要： A method is disclosed for emulating a disk drive on flash memory, thus enabling one or more file-systems to be resident on flash memory. A list of data structures is maintained corresponding to certain sectors resident on flash memory. Certain characteristics of data access to those sectors are recorded and a weightage value is dynamically computed, which is used to select those sectors that remain cached. This weightage value is calculated so that it minimizes erases and speeds up writes to flash memory and also automatically detects flash memory sectors that hold critical meta-data information or frequently accessed files and gives preferential treatment to those sectors. The number of sector caches available to the device driver is configured depending on the memory available in the system.
摘要翻译：公开了一种用于在闪速存储器上模拟磁盘驱动器的方法，从而使得一个或多个文件系统驻留在闪存上。对应于驻留在闪存上的某些扇区，保持数据结构的列表。记录对这些扇区的数据访问的某些特性，并且动态地计算权重值，用于选择那些保持高速缓存的扇区。计算此重量值，以便最大限度地减少擦除并加快对闪存的写入速度，并自动检测保存关键元数据信息或频繁访问的文件的闪存扇区，并对这些扇区给予优先处理。可用于设备驱动程序的扇区缓存的数量根据系统中可用的内存进行配置。
