UG639 (v 12.2) July 23, 2010
Lesson 2 - Fixed Point and Bit Operations
Overflow and Round Modes
System Generator supports the overflow modes Wrap, Saturate and Flag as error. Wrap is the default because it has
the least cost in hardware. Saturate requires System Generator to insert logic to perform that operation and
therefore should only be used when necessary for the application
System Generator supports Truncate and Round of the LSB during the quantization process. Similar to the Wrap
mode for overflow mode, Truncat e has minimal hardware cost and is the default. Specifying the Round mode
requires System Generator to insert extra logic and should be used when only necessary for the application.
