Build 05 Specific Changes

Below is a list of changes and improvements specific to DADiSP 6.5 B05:

New Features and Functions

Faster Computation

B05 provides 20% to 40% faster execution by employing direct buffer based optimizations for the following series functions:

• Arithmetic Functions: +,-,*,/,^,%
• Relational Operators: <, <=, >, >=, ==, !=
• Logical Operators: &&, ||, !, AND, OR, NOT, XOR
• Bit Operators: >>, <<, &, |+, ~, bitor
• Trigonometric Functions: acoth, acsc, acsch, asec, asech, asin, asinh, atan, atanh, cos, cosh, cot, coth, csc, csch, sec, sech, sin, sinc, sinh, tan, tanh
• Special Functions: abs, ceil, exp, floor, log, log10

Even faster execution when combined with the new VectorXL Module to accelerate common vector math functions by an additional 20% to 60% resulting in a 2x to 4x performance increase over DADiSP 6.5 B04.
