VisSim/Fixed
Point lets you easily simulate the
behavior of fixed-point algorithms prior to code generation and
implementation of the algorithm on fixed-point hardware. You can
simulate fixed-point algorithms -- such as, controllers or filters --
together with floating point components -- such as, motor or amplifier
models -- to validate their behavior in a "virtual" system prototype.
When used in conjunction with VisSim/Embedded Controls Developer,
VisSim/Fixed Point produces highly efficient, fixed-point production
code to a Texas Instruments C2000 DSP or any fixed-point target
supporting a C compiler.
VisSim/Fixed
Point includes a comprehensive tutorial on fixed-point controller
design, along with an example of converting a floating-point controller
implementation to a fixed-point implementation.
Features
-
Automatic radix point scaling of all fixed-point
blocks and fixed-point operations to maximize dynamic range
-
Color highlighting at the block level for overflow
alerts
-
Use of high and low watermarks to determine
adequate headroom for radix point settings
-
Master word length control that enables the
fixed-point word length to be changed for the entire block diagram
-
Choose any word size between 1 and 32
-
"Smart" blocks: data-type-aware blocks that become
fixed- or floating-point based on the input data type
-
Intuitive dialog boxes to configure fixed-point
