+# The new bytecode
+
+We will reimplement VM to use 8bit instruction code. By
+bytecode, we mean real byte code. The whole purpose is
+reducing the memory consumption of mruby VM.
+
+# Instructions
+
+Instructions are bytes. There can be 256 instructions. Currently we
+have 94 instructions. Instructions can take 0 to 3 operands.
+
+## operands
+
+The size of operands can be either 8bits, 16bits or 24bits.
+In the table.1 below, the second field describes the size (and
+sign) of operands.
+
+* B: 8bit
+* sB: signed 8bit
+* S: 16bit
+* sS: signed 16bit
+* W: 24bit
+
+First two byte operands may be extended to 16bit. When those byte
+operands are bigger than 256, the instruction will be prefixed by
+`OP_EXT1` (means 1st operand is 16bit) or `OP_EXT2` (means 2nd operand
+is 16bit) or `OP_EXT3` (means 1st and 2nd operands are 16bit).
+
+For instructions marked by `'`, `OP_EXT1` can be prefixed. For those
+with `"`, either `OP_EXT1` or `OP_EXT2` or `OP_EXT2` can be prefixed.
