1.7.3. Java bytecodes

ARM architecture v6 with Jazelle technology executes variable length Java bytecodes. Java bytecodes fall into two classes:

Hardware execution

Bytecodes that perform stack-based operations.

Software execution

Bytecodes that are too complex to execute directly in hardware are executed in software. An ARM register is used to access a table of exception handlers to handle these particular bytecodes.

A complete list of the ARM1136JF-S processor-supported Java bytecodes and their corresponding hardware or software instructions is in the Jazelle V1 Architecture Reference Manual.
