    摘要: A resource domain controller in a data processing system stores information that is used to group various resources, such as bus masters and peripherals, into common domains. Each group can be referred to as a resource domain and can include one or more data processor and peripheral devices. The resource domain information is then used to determine whether a particular access request from a data processor is authorized to access its intended target, e.g., one of the peripheral devices, by determining whether the access request and the intended target each belong to a common resource domain. If so, the access request is allowed, otherwise the access request is prevented from being successfully completed.

    摘要: A semiconductor device includes a processing system including a section of power domain circuitry and a section of coin cell power domain circuitry. The coin cell power domain circuitry is configured to, when power is initially provided to the coin cell power domain circuitry, using power provided by a power management circuit as feedback to determine that the power management circuit provides the power in response to a power request signal being a toggle signal, and determine that the power management circuit provides the power in response to the power request signal being a pulse signal.

    摘要: A first complementary metal oxide semiconductor (CMOS) current reference circuit (100, 500) has a first and a second current mirror (110, 150) and is implemented using one of bulk wafer technology and silicon on insulator (SOI) technology. The first current mirror (110) has an output stage (130) that includes at least one cascode coupled field effect transistor (FET) (125) having one of a source tied well (when implemented using bulk wafer technology) or a source tied body (when implemented using SOI technology). A second CMOS current reference circuit (600, 800) has a first and a second current mirror (650, 610) and is implemented using SOI technology. The first current mirror (650) has a first bias FET (161) having a gate tied body.
