3)The existing MIPS32 instruction set includes integer multiplication and multiply-accumulate which delivers results into a double-size accumulator 4)SIMD instructions operating on 4 x unsigned bytes or 2 x 16-bit values packed into a 32-bit register 5)SIMD operations are basic arithmetic, shifts ...
单精度数(float型)在32位计算机中存储占用4字节,也就是32位,有效位数为7位,小数点后6位。 双精度数(double型)在32位计算机中存储占用8字节,也就是64位,有效位数为16位,小数点后15位。 浮点寄存器 在mips中一共有32个浮点寄存器(其中包含16个双精度浮点寄存器),用于单独处理浮点数 函数声明和调用 函数声明 ...
