decoder_nbuf.v

基于4个mips核的noc设计

module DECODER_NBUF(instr, instr_25_21, instr_20_16);
    input [31:0] instr;
    wire [31:0] instr;
    output [4:0] instr_25_21;
    reg [4:0] instr_25_21;
    output [4:0] instr_20_16;
    reg [4:0] instr_20_16;
    reg [31:0] t_instr;
    reg [4:0] t_instr_25_21;
    reg [4:0] t_instr_20_16;
    
    always @(instr)
        begin : decoder_nbuf_thread
            t_instr = instr;
            t_instr_25_21 = t_instr[25:21];
            t_instr_20_16 = t_instr[20:16];
            instr_25_21 = t_instr_25_21;
            instr_20_16 = t_instr_20_16;
        end
