Not much understanding of the FPGA global Clock, thus reprinted a document:Http://xilinx.eetop.cn/?action-viewnews-itemid-42At present, synchronous sequential circuits are generally recommended for large designs. The synchronous sequential circuit is based on the design of Clock trigger, which puts forward higher requirements for clock cycle, duty ratio, delay and jitter. In order to meet the requirements of synchronous timing design, the design of th

Memory allocation of a program The memory consumed by a program compiled by C + + is divided into the following sections: 1, stack area (stack)-by the compiler automatically assigned to release, store the function of the parameter values, local variables and other values. The operation is similar to the stack in the data structure. 2, heap area (heap)-Generally by the programmer assigned to release, if the programmer does not release, the program at the end may be reclaimed by the OS. Note that

What is a global variable? A global variable , also known as an external variable, is defined outside the function and is scoped to the end of the program file, starting at the definition of the variable.
