8051 Core FPGA verilog 完整
应用背景Logical separation of program and data memory
All 8051 devices have specific memory organization, they have separate address spaces
for Program (ROM) and Data (RAM) Memory. This logical separation of Memory is
useful because it allows the Data Memory to be accessed by 8-bit addresses, which can
obviously be more quickly stored and manipulated by an 8-bit CPU. Of course, the l6-bit
Data Memory addresses can still be generated with the DPTR register.
Program Memory
Program Memory can only be read, not written to. The address space for 8051 core is 16-
bit, so there is maximum of 64K bytes of Program Memory. Up to 4 Kbytes of Program
Memory can be on chip, internal Program Memory of the 8051 core. For access to
external Program Memory is used signal PSEN (Program Store Enable).
Data Memory
Data Memory is on a separate address space than Program Memory. For external Data

SD卡和AIC23数字音频输出实验, FreeDev Audio Dsp Board采用了TI公司的TVL320AIC23
1、控制接口使用I2C,Quartus中将CS置低(器件地址0011010)。 2、数字音频接口使用了组件FreeDev_aic23,有三种测试和应用
模式,中断结合DMA方式能在NIOS II中采集和发送数据。中断信号 产生于模块中FIFO缓冲区的半满信号,读取数据端口自动清除中断
请求信号。 3、I2C IP 和FreeDev_aic23 IP分别在Quartus 工程目录中 4、SD卡读写通过SD_DAT0、SD_CLK、SD_CMD三个PIO信号线用软件 控制时序。 5、该范例读SD卡数据,通过DMA将Buffer数据送到FreeDev_aic23的
FIFO中实现数据播放。 6、SD卡中的数据必须是以48K*16bit保存的采样数据。数据可以通过SD读卡器写入。
