  • Patent number: 8145961
    Abstract: The present invention relates to the architecture and operation of computer hardware memory logic, and in particular to a method and respective system for verifying hardware memory logic, wherein an Error Correction Code (ECC) is used for correcting single-bit or multi-bit errors when the ECC-bits cannot be accessed directly for a read or write process. The system and process employs the selection of data patterns that produce check bits that are all ones to ferret out errors in the ECC circuitry.

  • Publication number: 20100313061
    Abstract: A method provides exception handling for a computer system. As an error in the computer system's hardware is detected, an exception vector pertaining to the hardware error is determined, and execution flow is transferred to a dispatcher that corresponds/pertains to the exception vector. A specific instance of a plurality of instances of a main exception handler is selected, and the specific instance of the main exception handler is executed. The actual exception handler thus contains two distinct parts, a dispatcher, which is unique and preferably resides in a safe memory region, and a main exception handler, multiple copies of which reside in an unsafe memory region.

  • Publication number: 20050149824
    Abstract: The present invention relates to the architecture and operation of computer hardware memory logic, and in particular to a method and respective system for verifying hardware memory logic, wherein an Error Correction Code (ECC) is used for correcting single-bit or multi-bit errors, and wherein the ECC-bits cannot be accessed directly for a read or write process. In order to improve ECC testing, an ECC verification is proposed.

  • Patent number: 6587002
    Abstract: The preferred embodiment describes a thermal controller (305) that provides protection for heat sensitive devices (310) within an amplifier module (315). A thermal sensing circuit (370) is used for detecting any increases in temperature surrounding the devices (310) and the output is provided to the thermal controller (305), wherein the thermal controller (305) provides a current-limiting control (445), a voltage control (440), and a status monitor control (450).
