Engine Pipeline

Data Encoding

Byte mode (0b0100) with 8-bit char count, terminator, and pad bytes (0xEC, 0x11) to fill 19 codewords.

Reed-Solomon

GF(2¸) primitive 0x11D. Generator degree-7 polynomial division to produce 7 EC codewords.

Matrix & Mask

21x21 layout: 3 finders, timing, data zigzag. All 8 masks evaluated; best selected by N1-N4 penalty scoring.

Format Info

BCH(15,5) encoding with XOR mask 0x5412 placed in two redundant sets around the finders.
