Integer type

The various contributions can also be classified in accordance with the optimization techniques used. However, this method of organization gives rise to an even more diverse classification, since the techniques used range all the way from rules of thumb (A3-A5, M6-M8, Ol, T2) and analytical solution (S8) to the more recent developments in mathematical programming. Most of the techniques reported are continuous, but some are discrete (C8, R5) and still others are of mixed integer types (G3). Table VI shows such a classification for the papers reviewed. It is clearly beyond the scope of this review to delve into the mathematical bases of these methods. We shall...

For an integer type, the maximum size is 32 bits and the number is assumed to be in 2 s complement form. Optionally a synthesis system may perform data flow analysis of the model to determine the maximum size of an integer variable. For example,... 

Here is an example in which the operands are signed numbers. This is achieved by using the integer type. 

Equality operators are modeled similar to arithmetic operators in terms of whether signed or unsigned comparison is to be made. Here is an example that uses signed numbers. Note that in this case, the operands of the equality operator are of integer type because values of this type represent signed numbers. 

Variables (reg and integer types) declared locally within an always statement do not infer flip-flops. This may potentially lead to a functional mismatch between the Verilog HDL model and the synthesized netlist. Here is an example of a locally declared variable Temp that does not get inferred as a flip-flop. 

As our last example in this section we will take a highlighted block of data, and raise all of its elements to some power, for which we will here select 3. (With an integer power it is somewhat easier to verily by simple inspection that the macro works properly. However, you are free to pick any other number, not necessarily either positive or integer.) Type the following macro, give it a shortcut key, and test it. 

Figure 1 shows a simple timed CPN example, D is defined to be colored set, colored set can be defined to be any data type, for example, in this figure, colored set D is defined to be integer type. Place A and Place C belong to coloredset D. Transition B transfers variable a from place A to place C . Function r() defines a stochastic function and assigns the value to variable t. It means variable a is transferred from place A to place C at time 0, the token in place C is valid at time t. At place A, d V is the initial token. 

Types. We support the downscahng of function types, integer types, pointer types and aggregate types such as arrays and structures. Since the AN-encoded... 

For downscaling integer types, we reduce their size according to our used scale factor. For sizes below 8 bit, we use 8-bit integers and after all instructions executed on these values, we execute a modulo with on the result to... 

Integers are the only numeric type supported for synthesis. An integer type is a set of integer values between a specified range. The upper and lower bounds of the range are vendor spedfic, but for fully portable code the limits specified in the predefined integer type INTEGER should be used, i.e. 

An integer type object can be used with any of the standard operators, but certain rules must be observed in order to create a synthesizeable description. These are discussed in section 6.1.2. 

The arithmetic operators in VHDL can operate on any predefined numeric type. For a synthesizeable design their use is dierefore limited to integer types. Box 6.1 illustrates ways of expressing synthesizeable numeric literals. The operators can be subdivided into die following classes.
