the resources available in Stratix II devices.
Each LAB consists of eight ALMs, carry chains, shared arithmetic chains,
LAB control signals, local interconnect, and register chain connection
lines. The local interconnect transfers signals between ALMs in the same
LAB. Register chain connections transfer the output of an ALM register to
the adjacent ALM register in an LAB. The Quartus
associated logic in an LAB or adjacent LABs, allowing the use of local,
shared arithmetic chain, and register chain connections for performance
and area efficiency.
