A 4-bit class identifier is added to the beginning of each compressed instruction to supply class
identification during decompression. Compressed and bypass field lengths may vary. (A fully bypassed
instruction, including its 4-bit class identifier, is 36 bits.)
The compressed instruction is guaranteed to start on an even bit. Thus, four bits are needed to find the
starting location of the instruction inside a memory word. The instruction address in decompression on
mode consists of a 28-bit word address (1 Gbyte of address space) and a 4-bit instruction pointer (IP). See

half. A bypassed field is one for which non-compressed data (16-bit halfword or 32-bit word) is
placed in the compressed code. After compression is defined, the non-compressed data field is
defined in the class.
