Module Description:
 
        This module defines constants that are going to be used
        all over the code. By know you have may noticed that all
        constants are pre-compilation define directives. This is
        for simulation perfomance reasons mainly.
*******************************************************************************/
 
`define MAX_CORES       4 //The number of cores, make sure you update MAX_CORE_BITS!
`define MAX_CORE_BITS   2 // 2 ^ MAX_CORE_BITS = MAX_CORES
`define MAX_TMEM_BANKS  4 //The number of memory banks for TMEM
//---------------------------------------------------------------------------------
//Verilog provides a `default_nettype none compiler directive.  When
//this directive is set, implicit data types are disabled, which will make any
//undeclared signal name a syntax error.This is very usefull to avoid annoying
//automatic 1 bit long wire declaration where you don't want them to be!

//---------------------------------------------------------------------------------
//Defines the Scale. This very important because it sets the fixed point precsision.
//The Scale defines the number bits that are used as the decimal part of the number.
//The code has been written in such a way that allows you to change the value of the
//Scale, so that it is possible to experimet with different scenarios. SCALE can be
//no smaller that 1 and no bigger that WIDTH.
`define SCALE        17
 
//The next 2 defines the length of the registers, buses and other structures, 
//do not change this valued unless you really know what you are doing (seriously!)

//Next are the constants that define the size of the instructions.
//instructions are formed like this:
// Tupe I:
// Operand                       (of size INSTRUCTION_OP_LENGTH )
// DestinationAddr (of size DATA_ADDRESS_WIDTH )
// SourceAddrr1  (of size DATA_ADDRESS_WIDTH )
// SourceAddrr2  (of size DATA_ADDRESS_WIDTH )  
//Type II:
// Operand                       (of size INSTRUCTION_OP_LENGTH )
// DestinationAddr (of size DATA_ADDRESS_WIDTH )
// InmeadiateValue (of size WIDTH = DATA_ADDRESS_WIDTH * 2 )
//You can play around with the size of instuctions, but keep
//in mind that Bits 3 and 4 of the Operand have a special meaning
//that is used for the jump familiy of instructions (see Documentation).
//Also the MSB of Operand is used by the decoder to distinguish 
//between Type I and Type II instructions.

//an inmediate value instead of a register address!
//Another example is that in the JUMP family Bits 3 and 4 have a special
//meaning: b4b3 = 01 => X jump type, b4b3 = 10 => Y jump type, finally 
//b4b3 = 11 means Z jump type.
