Abstract: Embodiments disclosed herein relate to split rail architecture for power supplies in a system, and more particularly, to providing isolation and control of a power supply. In an example, an integrated circuit device is provided that includes a device voltage supply, an input/output (I/O) voltage supply coupled to the device voltage supply, and a level shifter circuit coupled to the I/O voltage supply. The level shifter circuit includes a pair of cross-coupled p-type metal-oxide semiconductor field effect transistors (PMOS transistors), a pair of n-type transistors (NMOS transistors) coupled between the pair of cross-coupled PMOS transistors and a ground connection, and an inverter circuit coupled to the device voltage supply and the level shifter circuit. The level shifter circuit further includes a capacitor coupled to the pair of cross-coupled PMOS transistors and the ground connection and is in parallel with respect to a first one of the pair of NMOS transistors.

Abstract: Various examples disclosed herein relate to digital signal processing, and more particularly, to identifying metrics of audio samples to dynamically adjust the gain of audio data. In an example embodiment, a pulse density modulation system is provided that includes sample generation circuitry and gain control circuitry coupled to the sample generation circuitry. The sample generation circuitry is configured to sample audio data to produce samples of the audio data and output the samples to a processor and to the gain control circuitry. The gain control circuitry is configured to determine one or more metrics based on the samples of the audio data and output the one or more metrics to the processor.

Abstract: A microcontroller is provided and comprises a central repository, a processing device, and a firewall. Rule repository memory in the central repository stores one or more access rules defining an access permission of a software context to one or more target resources of the microcontroller. The firewall receives a bus transaction initiated based on an instruction and determines whether any access rule stored in memory of the firewall defines the access permission of the software context to a destination resource. If no access rule stored in the firewall memory defines the access permission, the firewall communicates a miss query condition to the central repository. The central repository searches the rule repository memory for an access rule defining the access permission of the software context to the destination resource, and if a related access rule is found, the related access rule is stored in the firewall memory.

Abstract: An electronic system includes a repair MMR coupled with a first SRAM module within a plurality of SRAM modules coupled with each other in a daisy-chain configuration on a repair interface, and coupled with a last SRAM module within the plurality of SRAM modules via the repair interface. The electronic system also includes storage memory configured to store repair data for the plurality of SRAM modules and repair instructions, and processing circuitry. The processing circuitry is configured to, during boot up of the electronic system, read repair data for one or more of the plurality of SRAM modules from the storage memory, create serialized repair data for one or more the plurality of SRAM modules based on the repair instructions and the repair data, and to sequentially transmit the serialized repair data to the MMR.
