| In each iteration, the program checks if the current instruction is +/,/-/./</>/[/] (in that order). If it obtains a match, it executes the instruction, but does not restart the loop; eg if there is a "++" sequence, it executes the first one but compares the second one to a , then - etc, and cycles back to plus. | |
| The tape is configured as follows: | |
| 1 = instruction counter (no of instructions executed in current iteration)* | |
| 2 & 3 = program counter PC | |
| 4 & 5 = tape counter TC | |
| 6 = bracket counter (for nested brackets) BC | |
| 7 = buffer (always 0 except for copying purposes) | |
| 8 = beginning of input program T1 (always 255 except for copying purposes) | |
| 9 etc = input program; each instruction takes 4 cells (x; x; 255; 255) |
This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Keep it simple, stupid. You ain't gonna need it.
This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of
