Shatov (Meister)" Date: Tue, 1 Oct 2019 15:05:11 +0300 Subject: Further work on the Montgomery modular multiplier. Can now to the "triangular" part of multiplication, i.e. compute the "magic" reduction coefficient Q = LSB(AB) * N_COEFF. --- rtl/modexpng_mmm_fsm.vh | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'rtl/modexpng_mmm_fsm.vh') diff --git a/rtl/modexpng_mmm_fsm.vh b/rtl/modexpng_mmm_fsm.vh index c237a0b..2700a42 100644 --- a/rtl/modexpng_mmm_fsm.vh +++ b/rtl/modexpng_mmm_fsm.vh @@ -19,6 +19,16 @@ localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_SQUARE_COL_N_TRIG = 15; localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_SQUARE_COL_N_BUSY = 16; localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_SQUARE_HOLDOFF = 17; + +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_COL_0_INIT = 21; +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_COL_0_TRIG = 22; +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_COL_0_BUSY = 23; + +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_COL_N_INIT = 24; +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_COL_N_TRIG = 25; +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_COL_N_BUSY = 26; +localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_MULT_TRIANGLE_HOLDOFF = 27; + localparam [FSM_STATE_WIDTH-1:0] FSM_STATE_STOP = 999; \ No newline at end of file -- cgit v1.2.3 crypto software, HSM management, RPCgit repositories
