请问TMS320C6415/6416有IQMATH库吗?

最近采用6416进行定点运算,请问有官方IQMATH库吗?我查了下,只有c64+的

IQmath是做浮点的吧~~~

我所理解的浮点是float和double型的,IQMATH数据类型小数位是固定的,计算精度跟数据动态范围矛盾,是我理解不深入?请问有6416有IQmath库吗?

没有C64的IQMATH库,就用RTS库里的吧。
下面句子关于IQMATH的描述:
However, C64+ DSP core does not support floating point operations in hardware;floating point operations on this platform will take place in software such as a C program. The standard run time support library will allow you to do floating point operations in C code as it is, though if you are looking for additional performance beyond the standard RTS there is an IQMath library for the C64x+ available that may be of some help.
