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： A comb light source and spectrometer is disclosed. The comb light source and spectrometer can include a plurality of light emitters, where each light emitter can be configured to emit light included in a plurality of wavelength bands. Each wavelength band can be separated from an adjacent wavelength band by a noise band. Due to the separated wavelength bands for a light emitter, any signal received outside of the one or more wavelength bands can originate from noise (e.g., drift, ambient light, electrical noise), thereby enhancing signal analysis and noise rejection. In some examples, the comb light emitters can be activated sequentially such that a plurality of wavelengths across a spectrum can be measured. In some examples, the resolution and the number of spectral lines in the comb light source can be tuned by changing the properties of the quantum dots and/or increasing the number of comb light emitters.
