This application note describes how the existing dual-port block memories in the Spartan™-IIand virtex™ families can be used as Quad-Port memories. This essentially involves a dataaccess time (halved) versus functionality (doubled) trade-off. The overall bandwidth of the blockmemory in terms of bits per second will remain the same.
