Read @Burstlenght > 2

[axel6644]

Hi,

to save more than the default numbers of words (BURST_LENGTH == 2) i did the following modification @ process "latch_sdram_data"

signal word_cnt_int : natural range 0 to BURST_LENGTH-1;

if first_word = '1' then q_reg(DATA_WIDTH-1 downto DATA_WIDTH-SDRAM_DATA_WIDTH) <= sdram_dq; word_cnt_int <= 1; --initwert elsif read_done = '1' then q_reg(SDRAM_DATA_WIDTH-1 downto 0) <= sdram_dq; valid <= '1'; elsif word_cnt_int > 0 then -- 2. Word.... q_reg(DATA_WIDTH-1 - word_cnt_intSDRAM_DATA_WIDTH downto DATA_WIDTH - word_cnt_intSDRAM_DATA_WIDTH -SDRAM_DATA_WIDTH) <= sdram_dq; word_cnt_int <= word_cnt_int+1; end if;

-- if first_word = '1' then -- q_reg(31 downto 16) <= sdram_dq; -- elsif read_done = '1' then -- q_reg(15 downto 0) <= sdram_dq; -- valid <= '1'; -- end if;
