VLSI Design of 128-Point Pipeline FFT/IFFT Processor
VHDL is an acronym for VHSIC Hardware Description language (VHSIC stands for Very High Speed Integrated Circuits). It is a hardware description language that can be used to model a digital system at many levels of abstraction ranging from the algorithmic level to the gate level. The complexity of the digital system being modeled could vary from that of a simple gate to a complete digital electronic system or anything in between. VHDL can be regarded as an integrated amalgamation of the following languages: sequential + concurrent + netlist + timing specification + waveform generation language. Therefore the language has constructs that enable to express the concurrent or sequential behavior of a digital system with or without timing.
