There is no "universal" answer. It depends on the instruction. Instructions can take one or more cycles depending on what they do. There are also instructions that can be executed in parallel. For the 28x CPU, you can find the cycle information in www.ti.com/lit/SPRU430. For the CLA, you can find this information in the TRM, www.ti.com/lit/SPRUII0. For the ARM core, please refer to https://developer.arm.com/documentation/100166/0001/.
