In recent years, several articles have proposed their own solutions to the above HBM problems, such as HBM Connect and Memory Access Optimizer IP core. HBM Connect uses a selective structure based on the butterfly switching network which could achieve higher effective bandwidth due to this characteristics. The butterfly network reduces its hop distance at the later stages of the custom crossbar. But it is difficult to use in the case of multiple HBMs. For MAO IP core, its paper does not introduce its specific structure, so it would not be discussed here.
