摘要
An apparatus and method are disclosed for transferring data from a first core to a second core of an integrated circuit (IC). The first core includes first and second memory blocks (e.g., first and second portions of a first-in-first-out (FIFO) memory coupled to first and second pre-multiplexers, respectively). The second core includes a multiplexer including first and second inputs coupled to the first and second memory blocks, respectively. Additionally, the second core includes a read controller configured to generate a first read control signal to cause the first and second memory blocks to transfer data to the first and second inputs of the multiplexer, respectively; and generate a second read control signal to cause the multiplexer to transfer data from the first and inputs to an output of the multiplexer.
