Abstract

An integrated circuit package includes a memory integrated circuit die and a coprocessor integrated circuit die that is coupled to the memory integrated circuit die. The coprocessor integrated circuit die has a logic sector that is configured to accelerate a function for a host processor. The logic sector generates an intermediate result of a computation performed as part of the function. The intermediate result is transmitted to and stored in the memory integrated circuit die.
