请教ASIC做查找表，一般用寄存器吗？有没有好的办法呢？

我想在系统启动的时候，配置rst_info_mem变量，16个周期配置一次，有没有什么好的办法呢?
reg [31:0] cnt;
always @ (posedge i_clk)
if (~i_rst_n)
cnt <= #UDLY 32'h0;
else if ( cnt ！= 32'ha0)
cnt <= #UDLY cnt + 'b1;
reg rst_info_mem [76:0];
always @ (posedge i_clk)
case(cnt)
32'h10://B1
rst_info_mem <= 77'h1209090c580000026204;
32'h20://B2
rst_info_mem <= 77'h1408051000000000ffff;

我想知道，是用单个寄存器还是寄存器组，上面的例子是单个寄存器，每隔16个周期赋值一次，
或者我们可以定义一个寄存器组 reg [76:0] rst_info_mem [8:0];然后定义一个buffer，reg [76:0] rst_info_mem_buffer，然后每16个周期，rst_info_mem_buffer= rst_info_mem [N],
或者还有别的方法，比如，生成ROM，RAM什么的，但是我设计的是ASIC,请大家指教
