[comp.sys.dec] Instruction Execution Timings for MicroVAX II needed.

alex@husc6.harvard.edu (Alex Zatsman) (07/11/88)

I need instruction execution timing for MicroVAX  II  .   I  have
failed  to  get  any  from  DEC.  It seems that most manufactures
(Motorola being a nice exception)  don't  publish  data  of  this
kind.

I need something like the tables  in  M68000  and  M68020  user's
manual  (Appendix  D  and  Section 9 respectively), which contain
number of cycles each instruction takes to  execute  and  similar
timing for memory access for various Addressing Modes. My hope is
that somebody out there might have succeeded in getting  it  from
DEC,  or, maybe, ran some benchmarks to determine the timings.  I
would appreciate any help I could get.

I suspect that  there  aren't  many  people  interested  in  this
things, so it would be better to e-mail the information to me in-
stead of posting it on the net.

Thank you.
