    摘要: A supply switch circuit is provided for implementing a switchable on-chip high voltage supply. A stack of transistors is coupled between an on-chip high voltage supply and a circuit node. A control signal is coupled to the stack of transistors for selectively switching the high voltage supply to the circuit node. The control signal is coupled to a voltage divider included with the stack of transistors to limit a maximum node voltage within the stack of transistors.

    摘要: Method and systems for dynamically recovering from voltage droops are disclosed. In one embodiment, a microprocessor coupled to a plurality of voltage sensing circuits is provided. The microprocessor includes an instruction sequencing unit and pipeline including a first series of instructions. A central voltage droop detection processor may be coupled to each of the voltage sensing circuits and the microprocessor. Voltage droop is detected using a voltage sensing circuit, after which processing of the microprocessor is interrupted. The pipeline may then be cleared. Subsequently, a second series of instructions including the first series of instructions, and additional instructions are issued. The additional instructions may include stall instructions that cause a delay in processing of the first series of instructions, which prevents re-occurrence of the voltage droop. The interruption and re-issuing also signals the microprocessor that all the data in a particular instruction stream might not be valid and allows recovery.

    摘要: A synchronization system capable of simultaneously resetting frequency divide-by counters (124A, 124B) of multiple processors (A, B) to zero regardless of the divide-by frequency signal (Mclk/n signal (168A, 168B)) and regardless of the magnitude of the clock mesh delays experienced by the Mclk/n signals in the processors. The synchronization system includes a mesh delay circuit (176A, 176B) for each processor that simulates in the undivided signal (Mclk/1 signal (136A, 136B)) the clock mesh delay experienced by the Mclk/n signal in that processor so as to provide an Lclk signal (172A, 172B). A phase detector detects the phase offset between the Mclk/n signal and the Sysclk signal (112) and sends an asynchronous offset signal (194A, 194B) to a counter re-setter (196A, 196B) that resets the divide-by counter to zero based on the offset signal.
