    摘要： A PBIST architecture is described. A data path circuit is configured for bit-to-associated bit comparisons of expected result data read from a tile with the expected result data read from result memory. The data path circuit is configured to write a first type of failure indication to first failure memory responsive to a data 0 being read from the result memory and a data 1 being read from the tile for a bit-to-associated bit comparison failure. The data path circuit is further configured to write a second type of failure indication to second failure memory responsive to a data 1 being read from the result memory and a data 0 being read from the tile for the bit-to-associated bit comparison.

    摘要： A programmable characterization-debug-test engine (PCDTE) on an integrated circuit chip. The PCDTE includes an instruction memory that receives and stores instructions provided on a chip interface, and a configuration memory that receives and stores configuration values provided on the chip interface. The PCDTE also includes a controller that configures a plurality of address counters and data registers in response to the configuration values. The controller also executes the instructions, wherein read/write addresses and write data are retrieved from the counters in response to the instructions. The retrieved read/write addresses and write data are used to access a memory under test. Multiple ports of the memory under test may be simultaneously accessed. Multiple instructions may be linked. The instructions may specify special counting functions within the counters and/or specify integrated (linked) counters. The PCDTE may transmit information off of the chip to exercise transmit/receive circuitry of the chip.

    摘要： A method, system, and computer program product are used for enhancing quality of contact lists for direct marketing campaigns. An embodiment of the method includes receiving a contact list that includes a plurality of customer profiles, and performing at least one of a counts verification check, a criteria outlier check, a data values check, and an output file check on the contact list. The method performs the aforementioned checks based at least partially on one or more quality check (QC) parameters. Further, the method includes generating a QC report that includes error statistics pertaining to at least one of the aforementioned checks. The method further generates an exceptions report based on the QC report and the QC parameters, and modifies the QC parameters based on the exceptions report.

    摘要： Methods of widening the permission for a memory access in a data processing system having a virtual cache memory and a translation lookaside buffer are disclosed. A memory access operation is initiated on a predetermined memory location based on logical address information and permission information associated with the memory access operation. The virtual cache memory is accessed and a determination may be made if there is a match between logical address information of the memory access operation and logical address information stored in the entries of the virtual cache. In the event of a match, then a determination may be made based on the permission information of the memory access operation and the permission information of the particular entry of the virtual cache memory as to whether the memory access operation is permitted. If the memory access operation is not permitted by the permission information of the particular entry of the virtual cache memory, then the translation lookaside buffer may be accessed based on the logical address information of the particular entry of the virtual cache memory. If there is a match between the logical address information of the particular entry of the virtual cache memory and the logical address information of a particular entry of the translation lookaside buffer, then a determination may be made based on the permission information of the memory access operation and the permission information of the particular entry of the translation lookaside buffer as to whether the memory access operation is permitted by the permission information of the particular entry of the translation lookaside buffer. If the memory access operation is permitted by the permission information of the particular entry of the translation lookaside buffer, then the permission information of the particular entry of the virtual cache memory may be updated based on the permission information of the particular entry of the translation lookaside buffer and the memory access operation may be completed.
