how to calculate tripipe cycles?

Hello,

        I am modeing for tri-pipe cycle.The GPU i use is mali-t628. Through using  DS-5 streamline,I get  tri-pipe cycle data.

There are three classes of execution pipeline in the tripipe design: one handling arithmetic operations, one handling memory load/store and varying access, and one handling texture access.

    In theory, tripipe cycle <= ALU pipeline cycle + load/store pipeline + texture pipeline cycle(Due to pipeline parallelism). But i find tripipe cycle >>alu pipeline cycle + load/store pipeline cycle +texture pipeline cycle.

Is there any other operation in tripipe,besides ALU,load/store,texture operations?
