6.1 System Generator for DSP - Why does the parallel multiplier take less logic than the serial multiplier?

Description

General Description: 

The data sheet for the COREGen Multiplier states that to create a smaller core, use the serial multiplier instead of the parallel multiplier. When I implement a multiplier through SysGen, the parallel multiplier is smaller than the serial multiplier and no matter what options I set for the serial multiplier it is always larger. Why is this?

Solution

This is a known issue, and the reason this occurs is because IOs are always being registered and maximum pipelining is always set. 

 

This has been fixed in System Generator v6.2
