摘要： A multiphase resonant pulse generator (74) has N groups of N-1 switches (44,46,48) which, when activated, form N paths from a power supply (Vdc) to ground or a reference voltage. Here N is a positive integer greater than 2. Each of the paths includes an inductance (38,40,42) and N-1 switches. The signal outputs (X1, X2, X3) from each of the N paths are cross cooled to switches belonging to the other N-1 paths to activate or deactivate the groups of switches.

摘要： One embodiment of the present invention provides a system that facilitates pipelining cache coherence operations in a shared memory multiprocessor system. During operation, the system receives a command to perform a memory operation from a processor in the shared memory multiprocessor system. This command is received at a bridge that is coupled to the local caches of the processors in the shared memory multiprocessor system. If the command is directed to a cache line that is subject to an in-progress pipelined cache coherency operation, the system delays the command until the in-progress pipelined cache coherency operation completes. Otherwise, the system reflects the command to local caches of other processors in the shared memory multiprocessor system. The system then accumulates snoop responses from the local caches of the other processor and sends the accumulated snoop response to the local caches of other processors in the shared memory multiprocessor system.

摘要： Some embodiments of the present invention provide a system that adaptively charges a battery, wherein the battery is a lithium-ion battery which includes a transport-limiting electrode governed by diffusion, an electrolyte separator and a non-transport-limiting electrode. During operation, the system determines a lithium surface concentration at an interface between the transport-limiting electrode and the electrolyte separator based on a diffusion time for lithium in the transport-limiting electrode. Next, the system calculates a charging current or a charging voltage for the battery based on the determined lithium surface concentration. Finally, the system applies the charging current or the charging voltage to the battery.

摘要： A system which starts up and shuts down a resonant oscillator circuit. During start up, the system operates a driving circuit, which is external to the resonant oscillator circuit, wherein the driving circuit uses a first clock signal to control a first phase output of the resonant oscillator circuit. At the same time, the driving circuit uses a second clock signal to control a second phase output of the resonant oscillator circuit, wherein the first and second clock signals have opposite phases. While the first and second phase outputs are being controlled, the system ramps up an input voltage, which is used to power the resonant oscillator circuit, wherein the ramping takes place across multiple initial oscillation periods. During shut down, the system shuts down the resonant oscillator circuit by ramping down the input voltage. Next, the system clamps the first and second phase outputs to a fixed voltage.
