Q: Why should you use Single Instruction, Multiple Data (SIMD) architecture to improve the performance of your Android mobile or IoT apps?

A: SIMD architecture allows you to parallelize code execution. This means that you can perform the same operation on an entire sequence, or vector, of data during one instruction. The result is performance improvement.

Q: What do the terms truncate and convolution mean?

A: Truncate: To truncate something is to shorten it or cut part of it off. In computer science, truncate is often used to describe data types or variables, like floating-point numbers and strings. For example, a function may truncate the decimal portion of a floating-point number to make it an integer.

Convolution: In computer science, specifically formal languages, convolution  is a function which maps a tuple of sequences into a sequence of tuples. Convolution is sometimes called zip. The name zip refers to the action of a zipper that interleaves two formerly disjoint sequences.

Q: How do you invoke a native library from your Java code?

A: To get data from the C++ library, you must create a binding between the Java method and the native library function.
