Hi all: I use the tool "Enable clock" try to test how much time the single -cycle instruction need, EX: mvkl .s2 0x0001,b0 The resule of the view window show => 6 clocks ==>so "mvkl .s2 0x0001,b0" spend 6*6.7ns = 40.2 ns (the c6711 one clock time = 6.7ns) The single -cycle instruction means the instruction will be execute in one cpu cycle? Are there any mistake above ? Please correct me! Thanks!! Fjulink |

Fjulink- Instead of one instruction, you might try averaging several instructions, maybe 100, to get a more accurate figure. Try with cache on and with off.
