<p> If <tt>l.jalr</tt> and <tt>l.jr</tt> generate effective addresses without word alignment they do not generate an alignment exception in Or1ksim. </p> <p> This is in part a documentation error. The architecture manual should make clear whether these instructions generate an alignment exception or just truncate the effective address. </p> <p> Reported in <em>Implementation and Verification of a CPU Subsystem for Multimode RF Transceivers</em> by Waqas Ahmed of the Royal Institute of Technology, Sweden. </p> <p> Jeremy </p> <p> -- <br /> Tel: +44 (1590) 610184<br /> Cell: +44 (7970) 676050<br /> SkypeID: jeremybennett<br /> Email: <a href="mailto:jeremy.bennett@embecosm.com">jeremy.bennett@embecosm.com</a><br /> Web: <a href="http://www.embecosm.com">www.embecosm.com</a> </p>
