Abstract: A system includes a power profile engine, a power measurement engine, and a power throttling signal generator. The power profile engine receives a desired power profile, e.g., a first profile current average associated with a first time duration and a second profile current average associated with a second time duration. The power measurement engine measures current being drawn and generates a first running average for the measured currents for the first time duration and generates a second running average for the measured currents for the second time duration. The power throttling signal generator generates a first power throttling signal to throttle power in response to the first running average for the measured currents being greater than the first profile current average and generates a second power throttling signal to throttle power in response to the second running average for the measured currents being greater than the second profile current average.

Abstract: A new approach is proposed to support a hardware-based lock mechanism having a hardware-based lock unit associated with a resource, wherein the lock is utilized by an arbitrator to arbitrate between multiple agents requesting access to the resource. When a first agent requests access to resource in unlocked state, the arbitrator creates a lock ID and set a locked state indicating that the resource is locked. The lock ID is provided to the first agent, which now has exclusive control over the resource. The arbitrator ensures that any agent with the same ID may access the resource. When a second agent requests access to the resource with a lock ID to the arbitrator, it is granted access to the resource if the lock ID provided matches the one stored on the lock unit. If there is a mismatch between the lock IDs, access to the resource is denied.

Abstract: A new approach is proposed that contemplates systems and methods to support post reset fuse reload for latency reduction. First, values of fuses are read once and stored into one or more load registers on an electronic device, wherein the load registers are protected. Once the values of the fuse are loaded into the load registers, a valid indicator of the load registers is set indicating that the values have been successfully loaded into the load registers. When other components of the electronic device need to access these values, the other components will check the load registers first. If it is determined that the valid indicator of the load registers is set, the stored values are read from the load registers instead of from the fuses. If the valid indicator of the load registers is not set, the values are loaded again from the fuses into the load registers.

Abstract: A new approach is proposed to support hardware-based PCIe link up based on post silicon characterization of an electronic device. A non-volatile storage medium of a bootup unit on the electronic device maintains an initialization sequence for the physical layer of a PCIe link, and a non-volatile storage medium allows flexible programming. During operation, the bootup unit reads from the non-volatile storage medium instructions to program/override one or more PCIe physical layer settings and controller registers for the PCIe link based on the post silicon characterization of the electronic device. The bootup unit is limited to access and override only to the one or more physical layer settings and controller registers of the PCIe link. The entire process of reading the initialization sequence and programming the one or more PCIe physical layer settings and the controller registers happens within time limit constraints of the PCIe specification for latency reduction.

Abstract: A new approach is proposed to support hardware-based protection for registers of an electronic device. Sources requesting access to the registers are categorized into a set of internal sources that can be trusted and a set of external sources that are untrusted. The registers are classified into a set of internal registers allowed to be accessed by the internal resources only, a set of read-only external registers that can be read by the external resources in addition to accessed by the internal resources, and a set of read/write external registers that can be read and written by both the internal and the external resources. Each access request by a source to the registers includes the source type, wherein access request is granted or denied based on the matching between the source bits in the access request and the register classification bits of the one or more registers to be accessed.
