  • Patent number: 7293258
    Abstract: A data processor has a debug circuit arranged to monitor whether operand data used for execution of a program meets a debug exception condition. The debug exception condition tests a two or more of multi-bit subfields of a vector operand independently. Debug action is taken if one or more of the multi-bit subfields meet the corresponding conditions.

  • Patent number: 7288834
    Abstract: The semiconductor device has a security coating with embedded magnetic particles and magnetoresistive sensors. This renders possible a measurement of the impedance of security elements defined by magnetoresistive sensors and security coating. If initial values of the impedance are stored, actual values can be compared therewith to see if the device has not been electrically probed or modified. Such a comparison can be used to check the authenticity of the device.

  • Patent number: 7290119
    Abstract: A memory accelerator module buffers program instructions and/or data for high speed access using a deterministic access protocol. The program memory is logically partitioned into ‘stripes’, or ‘cyclically sequential’ partitions, and the memory accelerator module includes a latch that is associated with each partition. When a particular partition is accessed, it is loaded into its corresponding latch, and the instructions in the next sequential partition are automatically pre-fetched into their corresponding latch. In this manner, the performance of a sequential-access process will have a known response, because the pre-fetched instructions from the next partition will be in the latch when the program sequences to these instructions. Previously accessed blocks remain in their corresponding latches until the pre-fetch process ‘cycles around’ and overwrites the contents of each sequentially-accessed latch.

  • Patent number: 7282982
    Abstract: Mixer-systems comprising gain-blocks (1-4) and switches (5-8) have a flexibility depending upon their configuration (insight) and are made more flexible (basic idea) by supplying data input signals to the gain-blocks (1-4) and oscillation signals to the switches (5-6) for switching couplings between the gain-blocks (1-4). A switch (5-6) comprises a switch-transistor and a gain-block (1-4) either comprises a gain-block-transistor or comprises five gain-block-transistors for increasing the linearity of the mixer-system. The switches (5-6) have main electrodes which in the balanced situation are all coupled via four impedances (13-16) to the gain-blocks (1-4). In the single ended situation two main electrodes are coupled via two impedances (13,15,18,20) to the gain-blocks (1-4) and two others are coupled directly to the gain-blocks (1-4). By introducing further switches (7-8) parallel to the switches (5-6), harmonics can be suppressed.
