以下是一个有9个输入输出端口的32位32位分支目标缓冲器的Verilog代码:
```
module branch_target_buffer (
input clk,
input [4:0] index_in1,
input [4:0] index_in2,
input [4:0] index_in3,
input [4:0] index_in4,
input [4:0] index_in5,
input [4:0] index_in6,
input [4:0] index_in7,
input [4:0] index_in8,
input [4:0] index_in9,
input [31:0] target_in1,
input [31:0] target_in2,
input [31:0] target_in3,
input [31:0] target_in4,
input [31:0] target_in5,
input [31:0] target_in6,
input [31:0] target_in7,
input [31:0] target_in8,
input [31:0] target_in9,
input [4:0] index_out1,
input [4:0] index_out2,
input [4:0] index_out3,
input [4:0] index_out4,
input [4:0] index_out5,
input [4:0] index_out6,
input [4:0] index_out7,
input [4:0] index_out8,
input [4:0] index_out9,
output reg [31:0] target_out1,
output reg [31:0] target_out2,
output reg [31:0] target_out3,
output reg [31:0] target_out4,
output reg [31:0] target_out5,
output reg [31:0] target_out6,
output reg [31:0] target_out7,
output reg [31:0] target_out8,
output reg [31:0] target_out9
);
reg [31:0] buffer [0:31];
always @(posedge clk) begin
target_out1 <= buffer[index_out1];
target_out2 <= buffer[index_out2];
target_out3 <= buffer[index_out3];
target_out4 <= buffer[index_out4];
target_out5 <= buffer[index_out5];
target_out6 <= buffer[index_out6];
target_out7 <= buffer[index_out7];
target_out8 <= buffer[index_out8];
target_out9 <= buffer[index_out9];
buffer[index_in1] <= target_in1;
buffer[index_in2] <= target_in2;
buffer[index_in3] <= target_in3;
buffer[index_in4] <= target_in4;
buffer[index_in5] <= target_in5;
buffer[index_in6] <= target_in6;
buffer[index_in7] <= target_in7;
buffer[index_in8] <= target_in8;
buffer[index_in9] <= target_in9;
end
endmodule
```
该模块有一个时钟输入和9个输入输出端口。每个输入端口都有一个5位索引和一个32位目标,用于将目标存储在缓冲器中。每个输出端口也都有一个5位索引,用于从缓冲器中检索目标。该缓冲器使用一个32位的RAM数组来存储目标,并在每个时钟上升沿时更新输出端口的值。
