[M4IF Technotes] Silicon solution for SP/ASP: how to divide?

[Gaurav Aggarwal]

Hi all,
Has anyone tried a silicon solution to SP/ASP? In particular my concerns
are:
1. Direct mode motion compensation in B-VOPs, requires division to
   compute (TRB * MVi) / TRD. Any ideas as to how to avoid the divisor
   in hardware? Do you guys know typical values of TRD, i.e., distance
   between two I/P VOPs? Most mpeg-2 encoders used a value of 3.
2. AC/DC coefficient prediction for IDCT requires a // dc_scaler or a
   // QP. Any ideas about this one?
Thanks for your advice!
Gaurav
