In computer science, read–modify–write is a class of atomic operations (such as test-and-set, fetch-and-add, and compare-and-swap) that both read a memory location and write a new value into it simultaneously, either with a completely new value or some function of the previous value. These operations prevent race conditions in multi-threaded applications. Typically they are used to implement mutexes or semaphores. These atomic operations are also heavily used in non-blockin… WebSep 23, 2024 · To do this, follow the steps below: Copy the DDR3/DDR4 SDRAM IP directory, for example: C:\Xilinx\Vivado\2015.3\data\ip\xilinx\ddr3_v1_0 Make your edits to the IP in this copied directory, and save the files anywhere.
