RC version of instruction set for BrainfuckPC relay computer. It support all +-<>[]., brainfuck instructions and a little bit more. Just because hardware allow me to do it.

Brainfuck mappings:

• ADD = +
• SUB = -
• ADA = >
• ADS = <
• JZP = [
• JNZ = ]
• IO.IN = ,
• IO.OUT = .

All instructions are 16-bit wide.

• Bits 15, 14, 13, 12 - define instruction class
• Bit 12 - Signed bit for Adder commands. Value of this bit extended to 13-15 bits when sending to adder input B;
• Bits 11-0 - contain least 12-bit of signed integer. Master 4 bits generates automatically: 0 for positive and 1 for negative values.

• AP - Address pointer Register
• IP - Instruction pointer register
• *AP - Current Data cell
• CIN - Console input
• COUT - console output
