PartialString – A finite-difference time-domain physical modelling synthesiser

https://differentinstruments.com/assets/gui.png
PartialString simulates the vibration of a plucked string by numerically solving the one-dimensional wave equation in real time using the finite-difference time-domain (FDTD) method. The string is represented as a list of displacements in memory. A lower note requires a longer string, which needs more points to represent it. You can then excite the string at any point along its length, and ...

A concrete explanation of how a cache works

https://parksb.github.io/images/54875045-80f32980-4e3a-11e9-8854-5cef63c9c58e.webp
A cache is a small, fast memory that sits inside the CPU chip, holding frequently used data to speed up processor access, and its performance is measured by hit latency and miss latency. To improve cache performance, you can shrink the cache to reduce hit latency, enlarge the cache to reduce the miss rate, or use a faster cache to reduce latency, and also optimize code to take advantage of ...
