the CPU uses registers, which are a form of permanent memory. By building registers into the CPU itself, those registers’ data can be accessed the millisecond it’s needed.
Zeolitic imidazolate frameworks (ZIFs) are a subset of metal–organic frameworks with more than 200 characterized crystalline and amorphous networks made of divalent transition metal centres (for example, Zn2+ and Co2+) linked by imidazolate linkers. ZIF

Stable recording of single-neuron activity, a phenomenon composed of sub-millisecond events, is vital to research aimed at understanding neuronal functions in brain tissue. Due to the source sizes of cell bodies, detection of signals with microscale spatial resolution is required, and thus needle ...
and TRL spectroscopies. There is a gap in the spectral coverage between 0.85 and 1.3 μm (Fig. 41 of Maurice et al.2020). The VIS range (covered by the violet and transmission spectrometers) has a somewhat smaller target footprint than the IR spectrometer (Table1). On Mars 2020, SuperCa...
The execution times, are sufficiently fast for de millisecond order of magnitude tasks. Regarding to the FPGA, here the speed is of no concern, but resource usage, especially the LUTs, is considerable. Nevertheless, here considerable optimization margin is still open. A significant difference is ...
Execution time.Unit tests are very quick, but end-to-end tests are very slow. Consider theRule of 1’sfor Web apps: a unit test takes ~1 millisecond, a service test takes ~1 second, and a Web UI test takes ~1 minute. If test suites have hundreds to thousands of tests at the upp...
