摘要:
Leakage current is reduced in a plurality of gates coupled between source storage elements and destination storage elements by waking the plurality of gates to allow current flow in response to assertion of any source clock enable signals that enable clocking of the source storage elements. The gates are slept to reduce leakage current in the plurality of gates, in response to assertion of a destination clock enable signal and all of the one or more source clock enable signals being deasserted, the destination clock enable signal enabling clocking of the destination storage elements.

A clock generator (622) includes a first circuit (812) and a second circuit (814). The first circuit (812) includes a first clock input configured to receive a first clock signal at a first frequency, a second clock input configured to receive a second clock signal at the first frequency, and an output. The second clock signal is out-of-phase with the first clock signal. The second circuit (814) is coupled to the first circuit (812) and includes a mode signal input configured to receive a mode signal. The output of the first circuit (812) is configured to provide a generated clock signal whose effective frequency is based on the first and second clock signals and the mode signal.
摘要:
To determine performance degradation at functional module in a normal power state due to a power control device, voltages are applied to oscillators at a power diagnostic module. A first voltage is a supply voltage for the data processing device, and a second voltage is a supply voltage applied at a functional module of the data processing device. Counters are adjusted based on the oscillators to determine the oscillators' respective frequencies. In addition, the power diagnostic module can include a timer to measure the length of time that the functional module is in a low-power state, and an analog to digital converter to measure the voltage applied to the functional module during transitions to and from the low-power state.

An integrated circuit (1600) includes a debug module (1602) and a clock generator (1610). The debug module (1602) is configured to receive a test pattern and provide a mode signal based on the test pattern. The clock generator (1610) includes a first clock input configured to receive a first clock signal, a second clock input configured to receive a second clock signal, and a mode input configured to receive the mode signal. The first and second clock signals are out of phase and have the same clock frequency. The clock generator (1610) is configured to provide a generated clock signal whose effective frequency is based on the first and second clock signals and the mode signal.
摘要:
A first transistor of a level shifter provides conductivity between a reference voltage and a node of the level shifter to hold a state of the level shifter output. When an input signal of the level shifter switches, additional transistors assist in reducing the conductivity of the first transistor. This enhances the ability of the level shifter to change the state of the output in response to the change in the input signal, thereby improving the writeability of the level shifter.
