    摘要: A field programmable gate array (FPGA) device including a non-non-programming-based default power-on electronic configuration. The non-non-programming-based default power-on electronic configuration defines a default state to initial a first logic function. Upon power-up, the FPGA device would be enabled to enter the default state without having first to be configured via a conventional programming mode, thus saving precious processing time during power-up. Several embodiments are disclosed, such as a mask via circuit, an asynchronized set/reset circuit, an unbalanced latch circuit and a flush and scan circuit. A related method is also disclosed to reduce the memory size dedicated to the first logic function to facilitate further programming after power-up. In addition to time saving and further programming, the FPGA device can also allow partial or incremental programming to expand the full functionality to match customer's different needs.

    摘要: A system, method and program product for determining a history state of data in a data retaining device are disclosed. A state of a partially-depleted silicon-on-insulator (PD SOI) device coupled to a data retaining device is measured to indicate a body voltage of the PD SOI device. The body voltage of the PD SOI device may indicate, among others, how long the PD SOI device has been idling, which indirectly indicates how long data in the data retaining device has not been accessed. As such, the current invention may be used efficiently with, e.g., a cache replacement algorithm in a management of the data retaining device.

    摘要: A system, method and program product for determining a relative amount of usage of a data retaining device are disclosed. A charge storing device is coupled to a data retaining device in a manner that a use of the data retaining device triggers a charging of the charge storing device. In a period that the data retaining device idles, charges in the charge storing device decay due to natural means. As such, a potential of the charge storing device may be used to indicate an amount of usage of the data retaining device. A comparison of the potentials of two charge storing devices coupled one-to-one to two data retaining devices may be used as a basis to determine a relative amount of usage of each of the two data retaining devices comparing to the other.

    摘要: The invention provides replacement operation code for specific defective lines of operation code contained in a ROM often on an ASIC chip which code is used in a processor. ROM memory constitutes the best use of chip space and is the most economical to manufacture of all of the various options. ROM memory is not changeable after it is set in ROM and, hence, if there is any change in the code (hereinafter sometimes faulty code) required after the code has been incorporated in the ROM memory, such change cannot be made in the ROM itself without replacing the entire ROM. The present invention allows change in any specific lines of faulty contained in ROM without replacing the entire ROM, and provides for changing only the faulty lines of code. It also allows the new code to have the same, more, or fewer lines than the faulty code.

    摘要: A way of dynamically modifying error recovery on a communications controller to operate at the lowest power mode allowed by current error rate conditions. When operating conditions are good and a small number of errors are detected, a low power error detection/correction mode is entered saving battery life. The low power error correction mechanism runs at a slower frequency and lower power than the high power mechanism and maintains the same data rate for the controller, thus saving power. Selecting the controller error (power) mode may be externally, such as by a person using a control dial on a cellular telephone when the voice data gets too noisy. Alternatively, the selection can be automatic, a critical error level detector internally making the selection.
