Description

Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Jazelle DBX
allows some ARM processors to execute Java bytecode in hardware as a
third execution state alongside the existing ARM and Thumb modes.
Jazelle functionality was specified in the ARMv5TEJ architecture and the
first processor with Jazelle technology was the ARM926EJ-S. Jazelle is
denoted by a ‚J‘ appended to the CPU name, except for post-v5 cores
where it is required for architecture conformance. Jazelle RCT is a
different technology and is based on ThumbEE mode and supports
ahead-of-time and just-in-time compilation with Java and other execution
environments.
