Due　to　the　complex　behavior　of　a　multiscroll　chaotic　system,　it　is　a　good　candidate　for　the　secure　communications.　In　this　paper,　by　adding　an　additional　variable　to　the　modified　Lorenz-type　system,　a　new　chaotic　system　that　includes　only　linear　and　piecewise　items　but　can　generate　4n　+　4　scroll　chaotic　attractors　via　choosing　the　various　values　of　natural　number　n　is　proposed.　Its　dynamics　including　bifurcation,　multistability,　and　symmetric　coexisting　attractors,　as　well　as　various　chaotic　and　periodic　behaviors,　are　analyzed　by　means　of　attraction　basin,　bifurcation　diagram,　dynamic　map,　phase　portrait,　Lyapunov　exponent　spectrum,　and　C0　complexity　in　detail.　The　mechanism　of　the　occurrence　for　generating　multiscroll　chaotic　attractors　is　presented.　Finally,　this　multiscroll　chaotic　system　is　implemented　by　using　the　Altera　Cyclone　IV　EP4CE10F17C8　FPGA.　It　is　found　that　this　FPGA-based　design　has　an　advantage　of　requiring　less　resources　for　0%　of　the　embedded　multipliers　and　0%　of　the　PLLs　of　this　FPGA　are　occupied.　©　2021　Faqiang　Wang　et　al.
