Excalibur ARM, epxa1,Design example • ug_xa1_devbd_getting_started • Can be download form here http://www.altera.com/literature/lit-exc.jsp • 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 Stripe Reg_file

A write request form stripe Single_transaction_slave Stripe 1 2 Reg_file

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 Stripe 1 4 3 2 Reg_file

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 + 0x00001000; 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)
