Signal Processing Blockset™ 6.7

Latest Features

Version 6.7

Released: 01 Mar 2008
 

Version 6.7, part of Release 2008a, includes the following enhancements:

• N-D support added to many blocks, including several blocks in the Statistics library
• Block parameter edit boxes support any built-in MATLAB data type other than Boolean and char

Version 6.0.1

Released: 22 Sep 2004
 

Version 6.0.1 includes bug fixes.

Version 6 (formerly DSP Blockset)

Released: 02 Jun 2004
 

New Features

• LPC to/from RC and G.711 Codec block
• Cascaded Integrator-Comb (CIC) decimation and CIC interpolation blocks
• Short-Time FFT and Inverse Short-Time FFT blocks
• Vector quantizer design, encoder, and decoder blocks
• More efficient code generation and faster simulation speed for LMS Filter blocks and Block LMS Filter blocks
• New Waterfall Scope

Fixed Point (Requires Simulink Fixed Point)

• Additional fixed-point data type support for statistics blocks (Min, Max, Variance), the Levinson-Durbin block, and many more. More than 85 blocks in the Signal Processing Blockset now support fixed-point data types.
• Expanded digital filter support: 14 new structures supporting fixed point and enhancements to the fixed-point implementation of biquad structures
• New fixed-point dialog interface enables you to set output data types (word size, binary points, rounding, overflow, etc.).
• Fixed-point support for Signal-to-Workspace and Signal-from-Workspace blocks
• New modes for most fixed-point blocks to automatically set fixed-point data types for block quantities. These modes ease the transition from floating point to fixed point by minimizing precision loss. Models can be customized to use less precision where appropriate.
