Automated identification of code changes
Implementations are described herein for automatically identifying, recommending, and/or automatically effecting changes to a source code base based on updates previously made to other similar code bases. Intuitively, multiple prior “migrations,” or mass updates, of complex software system code bases may be analyzed to identify changes that were made. More particularly, a particular portion or “snippet” of source code—which may include a whole source code file, a source code function, a portion of source code, or any other semantically-meaningful code unit—may undergo a sequence of edits over time. Techniques described herein leverage this sequence of edits to predict a next edit of the source code snippet. These techniques have a wide variety of applications, including but not limited to automatically updating of source code, source code completion, recommending changes to source code, etc. |

System for digital cancellation of clock jitter induced noise in a gyroscope with provides better power effect
In a digital gyroscope, the rate signal (including the quadrature) and the displacement signal of the drive part are sampled with an ADC. This displacement signal has the same frequency and phase as the quadrature signal that gets sampled in the rate channels. The displacement signal is sampled with the same clock as the rate signal resulting in the displacement signal having the same close-in phase noise folded into the signal band as the sampled quadrature in the rate signal. The sampled drive signal is subtracted from the sampled rate signal to eliminate the clock jitter induced noise in the rate signal. This relaxes the close-in phase noise requirement of the PLL and allows for a low power PLL implementation. |
