By expressing the new instructions as macros over existing instructions, the JVM only needs to be extended to support these macro instructions, not to support instructions specific to any one program.
The repeated instruction sequences for accessing fields have been factorized into macro instructions, as has the body of the constructors.
A multiplexor (MUX) that can accept instructions from either the instruction buffer or the Macro Instruction ROM and feed them to the instruction control unit is also associated with the instruction bus interface.
The Macro Instruction ROM (MIROM) is an on-chip ROM (1 K entries X 47 bits) that implements complicated instructions as sequences of simpler hardwired instructions; the opcode for the MIROM implemented instruction is effectively a branch target address into the ROM; the MIROM does not contain microcode.
