Simulink Fixed Point 6.2

Latest Features


Version 6.2

Released: 04 Sep 2009
 

Version 6.2, part of Release 2009b, includes the following enhancements:

See highlights and screen shots

  • Discrete Transfer Function block and new PID block that intrinsically support fixed-point
  • Enhanced Rapid Accelerator mode that supports parameters up to 128 bits
  • Enhanced Lookup Table (n-D) block, supporting parameter data types that are different from signal data types
  • Reduced memory use for evenly spaced breakpoints in Prelookup and Lookup Table (n-D) blocks
  • Integer division option to handle net slopes that are reciprocals of integers, with corresponding Model Advisor check to improve code efficiency
  • Enhanced Fixed-Point Advisor workflow
  • New diagnostics to detect precision loss in fixed-point constants

See the Release Notes for details.


Update Now


Version 6.1

Released: 06 Mar 2009
 

Version 6.1, part of Release 2009a, includes the following enhancements.

See highlights and screen shots 

  • Discrete Filter block now supports fixed-point data types
  • Prelookup and Interpolation Using Prelookup blocks now support parameter data types that differ from signal data types
  • Autoscaling support for Simulink signal objects using Fixed-Point Advisor and Fixed-Point Tool
  • New rounding modes convergent and round added to multiple blocks, enabling numerical agreement with embedded hardware and MATLAB results
  • Expanded support for simplest rounding mode that maximizes efficiency for blocks that handle mixed floating-point and fixed-point data types
  • Multiword generated code enhancements, including more efficient reuse of temporary variables

See the Release Notes for details.
