Cg中的条件操作符一个独特的性能是:支持向量运算。即,expr1的计算结果可以是bool型向量,expr2和expr3必须是与expr1长度相同的向量。举例如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 float3 h=float3(-1.0,1.0,1.0);float3 i=float3(1.0,0.0,0.0);float3 g=float3(1.0,1.0,0.0);float3 k...

IF/CASE/COND (ICC) expressions occurring within the HDL program that are not recognized by Verilog HDL are categorized and accordingly translated to IF/CASE statements in Verilog HDL syntax. For ICC expressions that are part of a conditional or binary operator expression, a globally incremental ...

Consider the foregoing example code, once values of the operands (e.g., the variables “a” and “b”) are obtained, and the operator (e.g., the comparator “>”) is applied to the operands, the processor 30 may be able to determine whether the condition of the conditional instruction...
