Before we get too excited about this, we should probably read ARM’s <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />US “7,131,118. Moore does have 3 patents listed as references, “584, “336, and “703, but there are 43 referenced patents in total, which IMO simply means that the USPTO performed a lot of DD when issuing this patent. The description of Prior Art does not list any of Moore’s patents, rather, only lists one, US “6,332,215 which of course is not part of the MMP. Yes it should mean that ARM was aware of the ‘336 & “584 back in July 25, 2002 when this ARM patent was filed, but not sure how it will effect our current litigation. AIMO. GLTAL

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to data processing systems. More particularly, this invention relates to data processing systems operable in a first mode to perform processing operations specified by JAVA.RTM. bytecodes and operable in a second processing mode to perform processing operations specified by other instructions.

2. Description of the Prior Art

It is known to provide data processing systems which can operate in a first mode to perform data processing operations specified by JAVA.RTM. bytecodes and operable in a second mode to perform data processing operations specified by other instructions. An example of such a system is described in United States Pending Patent Application entitled Unhandled Operation Handling In Multiple Instruction Set Systems and filed on 2 May 2002 and International Published Publication No. WO-A-02/29563. The disclosure of these documents is incorporated herein by reference.

U.S. Pat. No. 6,332,215 discloses a system which translates JAVA.RTM. bytecodes into native processor instructions and stores a copy of a JAVA.RTM. Local Variable within a register of the register bank of the native processor.

In the context of hardware acceleration of JAVA.RTM. bytecode execution measures which can improve execution speed are strongly desirable.
