摘要： Methods and apparatus for determining approximating polynomials using instruction-embedded coefficients are disclosed. In particular, the methods and apparatus use a plurality of coefficient values stored in a plurality of instructions. The coefficient values are associated with a runtime approximating polynomial of a K-th root family function. The coefficient values and the instructions stored in an instruction memory enable the processor system to determine a K-th root family function approximation value based on the runtime approximating polynomial.

摘要： Dynamic processor core switching is described. In embodiments, a multi-core processor system can include a first processor core that executes computer instructions at a first processing rate, and can include at least a second processor core that executes the computer instructions at a second processing rate, where the second processing rate is different than the first processing rate. A core profiler can generate system profile data that is evaluated to determine when a core-switch manager initiates switching execution of the computer instructions from the first processor core to the second processor core while the computer instructions are being executed.

摘要： An apparatus includes a processor to control a boot-up of an electronic device in response to a detection of tampering with the device. In some embodiments of the invention, the processor may detect tampering by authenticating a source of a boot image used during the boot-up; and the processor may detect tampering by verifying the integrity of the boot image. In some embodiments of the invention, the processor may control a transition of the electronic device from a first state to a second power state in response to a detection of tampering with the device. The electronic device consumes more power in the second power state than in the first power state.

摘要： A unique processor serial number may be utilized to augment a device key seed stored in a non-volatile memory. In this way, a relatively secure system may be enabled that facilitates renewing the device key. An integrated circuit may include a transport demultiplexer and key logic. The key logic communicates with the processor using a secure protocol. The key logic can generate random numbers that may be hashed with the processor serial number and the device key seed to generate a device key. The device key may be provided to a head end to facilitate secure communications between the head end and the client.

摘要： An over-the-air firmware update is accomplished in a secure manner using a two-step process. The first step uses an initial boot using a fixed boot program and an authenticated and verified secondary environment to complete starting of only authenticated code. After verifying a pending update, the second step is started with the electronic device being booted into an update mode with an update loader that has exclusive access to a signing key. A dummy update image is loaded into a temporary memory location and a hash is taken. A digital certificate is created corresponding to the update image and signed using the signing key. The update and digital certificate are atomically installed and the signing key is deactivated. Upon reboot, the new image is used for operation and is verified by the hash data and public key in the digital certificate.
