Abstract: A system and method is provided for monitoring interference in a wireless communication system. The system and method monitor error statistic data at one or more devices in a wireless communication system. The error statistic data can be utilized to determine the location of the interference. If any unusual error statistic data is present at the one or more of the devices, raw unprocessed data is provided from the devices experiencing unusual error activity. The raw unprocessed data can be utilized to characterize the interference. For example, the raw unprocessed data can be compared to one or more interference templates to determine an interference type. The raw unprocessed data can be compared between devices in the wireless communication system to determine the location of the interference with increased precision.

Abstract: A DSL modem (50). The DSL modem includes a connector (62) comprising a first pair of conductors (IP1, IP2) and a second pair of conductors (OP1, OP2). The DSL modem further includes both circuitry for transmitting according to a DSL protocol (52) and circuitry for receiving according to a DSL protocol (52). Still further, the DSL modem includes switching circuitry (60) operable to selectively switch to a first position to couple the circuitry for transmitting and the circuitry for receiving to the first pair of conductors and to a second position to couple the circuitry for transmitting and the circuitry for receiving to the second pair of conductors. Lastly, the DSL modem includes circuitry (52, CONTROL) for controlling the switching circuitry to switch to one of the first position and the second position and for then detecting whether DSL service exists along the pair of conductors to which the circuitry for transmitting and the circuitry for receiving is then coupled.

Abstract: A system and method for measuring die temperature of chips within an ATU-C modem and reporting the results to a central management entity such that, in the event of a thermal overload condition, an adaptive algorithm can change modem operation so a data connection can be maintained. The system and method may include integrating temperature detection sensors on each semiconductor device in an ATU-C modem chipset and the power supply module. The temperature sensors then report the die temperatures of each component in the chipset to the central management entity that can interact with the individual modem datapumps to manage power dissipation within the modem system.

Abstract: A display buffer includes a plurality of memory banks, each said bank having a plurality of ordered rows of data storage locations. Circuitry controls the storage of a plurality of sequenced lines of display data in said display buffer. A first set of lines of display data is stored at contiguous locations in a first memory bank with the first word of a first line being stored in a location offset from the first location of the first row so a last word of a last line is stored in the last location of the last row. A second set of lines is stored at contiguous locations starting at the first row of the second memory bank. A last line of the second set of lines is stored so that the last word of this last line is stored in the last location of a selected row of the second bank. A third set of lines is stored in a third memory bank starting at a memory line other than the first memory line.

Abstract: A circuit controls the reordering of data as it is transferred to control a memory. The data to be reordered is presented such that the ordinate bit position within a data word is uniquely associated with a particular input to a data bus. The bus inputs, however, are connected to the VRAM in an arrangement contrary to the desired ordinate association with the compressed data word. A single swizzle logic circuit operates to allow graphic compressed data to be reordered for presentation to the block-write inputs of a VRAM regardless of the VRAM or pixel size. The circuit relies upon properly expanding the compressed data prior to the actual reordering of the ordinate positions of the data bits. A method for controlling the reordering of data also is described.
