Excalibur ARM, epxa1,Design example ug_xa1_devbd_getting_started Can be download form here 這是一個簡單的 example, stripe 是唯一的 bus master, 只有它能送出 read 或 write 的 request, slave 則負責回映 master 的要求

The block diagram of this example Single_transaction_slave Reg_file Stripe

A write request form stripe Single_transaction_slave Reg_file Stripe 1 2

A write request from stripe Stripe 透過 AHB 送出一個 write request 到 single_transaction_slave, single_transaction_slave 的功用為負責處 理 AHB 上面的溝通訊號 Single_transaction_slave 將資料傳給 regfile 處理

A read request form stripe Single_transaction_slave Reg_file Stripe

A read request from stripe Stripe 透過 AHB 送出一個 read request 到 single_transaction_slave Single_transaction_slave 將資料傳給 regfile 處理 Regfile 將資料傳回給 single_transaction_slave Single_transaction_slave 將資料傳回給 stripe

Example Builds in epxa1 Download the example First hardware build Then software build download to development board Setup RS-232 connect in PC

Hardware build 先用 quartusII 打 開 example 按圖上的紐 開始 hardware build 通常不會有 問題除了 license Push here to build hardware

Software build 打開 SOPC Builder SDK Shell 進到 example 裡面的 gnu 資料夾中, 將 makefile 中的 epxa10.c 改為 epxa1.c 輸入 make

Download the design to development board 執行 prog_hw.bat 接下來就能看到板子 上面的跑馬燈

Setup RS-232 打開 hyperterminal 做 左邊圖裡面的設定

Example results 在板子上面能看到 LED 在跑動, 用 RS-232 和板子相連的 PC 也能夠在 hyperterminal 的視窗中看到以下的訊息 ************************************************************** ** Altera EPXA10 Development Board - I'm alive!!! ** ** ** Look for scrolling LEDs ** ** **************************************************************

修改 example-hardware What you want a write request do What you want a read request do Double click 在 regfile 的圖上

My Example reg_file.v if(write) begin if(reg_state) begin temp1 <= wdata; reg_state <= 1'b0; end else begin temp2 <= wdata; reg_state <= 1'b1; end end //endif else begin rdata <= temp1 + temp2; end

修改 example - software int main(void) { LED = (volatile unsigned int*) EXC_PLD_BLOCK0_BASE + 0x ; printf("\r\n"); printf("****************************************************\r\n"); printf("** **\r\n"); printf("** Altera EPXA10 Development Board - I'm alive!!! **\r\n"); printf("** **\r\n"); printf("** Look for scrolling LEDs **\r\n"); printf("** **\r\n"); printf("****************************************************\r\n"); while (1) Scroll_LED(); return 0; } 在 common 的資料夾內的 main.c

My Example main.c temp = *LED; while(tempc != 0){ printf("input first number :"); scanf("%d",&temp); *LED = temp; printf("input second number :"); scanf("%d",&temp); *LED = temp; temp = *LED; printf("temp = %d \r\n",temp); printf("continue?(1/0)\r\n"); scanf("%d",&tempc); }

My Example Results input first number :132 input second number :333 temp = 465 continue?(1/0)
