- 1. 准备工作
最近陆陆续续有工程师拿到了VCK190单板。 VCK190带Xilinx的7nm AIE，有很强的处理能力。 本文介绍怎么运行Xilinx AIE的例程，熟悉AIE开发流程。
本文先介绍Standalone（BareMetal）的例程， 它来自于Vitis-Tutorials 的 AIE a2z。
1. 准备工作
1.1. License
在上手之前，需要注意是VCK190 Production单板，还是VCK190 ES单板。如果是VCK190 Production单板，使用VCK190 Voucher，在Xilinx网站，可以申请到License。安装License后，License的状态窗口下，能看到下列项目。
代码语言：javascript复制AIEBuild
AIESim
MEBuild
MESim如果是VCK190 ES单板，需要在Lounge里申请"Versal Tools Early Eacess"; "Versal Tools PDI Early Eacess"的License，并在Vivado里使能ES器件。在Vivado/2020.2/scripts/init.tcl的文件里，添加“enable_beta_device xcvc*”，可以自动使能ES器件。
1.2. Platform
在进行开发之前，需要准备Platform。 VCK190 Production单板和VCK190 ES单板使用的Platform不一样，可以从下面链接下载各自的Platform，再复制到目录“Xilinx/Vitis/2020.2/platforms/”下。 VCK190 Production Platform VCK190 ES Platform
准备好后，目录结构与下面类似。
1.3. Common Images
Xilinx现在还提供了Common Images，包含对应单板的Linux启动文件，和编译器、sysroots（头文件、应用程序库）等。可以在Xilinx Download下载Versal common image。
1.4. 测试环境
Host OS： Ubuntu 18.04 Vitis 2020.2 PetaLinux 2020.2 VCK190 Production
2. AIE Standalone Flow
例程AIE a2z 是Standalone （BareMetal）的例程，Versal的A72不运行Linux。 它很全面，包含创建Platform、创建AIE Kernel、创建PL Kernel、创建A72应用程序、调试AIE Kernel。在Xilinx的文档中，AIE的程序，叫Kernel； 在Vitis里使用HLS开发的PL设计，也叫Kernel。
注意，2021年7月份，Vitis Tutorials的"master"分支，才包含例程AIE a2z 。
2.1. AIE a2z 分析
2.1.1. 文件列表
AIE a2z 包含下列文件。

aie_adder.cc
aie_graph.cpp
aie_graph.h
aie_kernel.h
host.cpp
pl_mm2s.cpp
pl_s2mm.cpp2.1.2. aie_adder.cc
aie_adder.cc是定义AIE Kernel的文件，也是最重要的文件，仿真和实际运行都需要。
AIE Kernel也很简单，相当于是C语言编程的HelloWorld, 只是读取2个向量，做加法运算后，再写出去。
代码语言：javascript复制void aie_adder(input_stream_int32* in0, input_stream_int32* in1, output_stream_int32* out) {
v4int32 a = readincr_v4(in0);
v4int32 b = readincr_v4(in1);
v4int32 c = operator (a, b);
writeincr_v4(out, c);
}2.1.3. aie_graph.cpp
aie_graph.cpp定义和控制运算的graph，这个例子中，只用于仿真。
代码语言：javascript复制#include "aie_graph.h"
PLIO* in0 = new PLIO("DataIn0", adf::plio_32_bits, "data/input0.txt");
PLIO* in1 = new PLIO("DataIn1", adf::plio_32_bits, "data/input1.txt");
PLIO* out = new PLIO("DataOut", adf::plio_32_bits, "data/output.txt");
// Hank： only for simulation??
simulation::platform<2, 1> platform(in0, in1, out);
simpleGraph addergraph;
connect<> net0(platform.src[0], addergraph.in0);
connect<> net1(platform.src[1], addergraph.in1);
connect<> net2(addergraph.out, platform.sink[0]);
#ifdef __AIESIM__
int main(int argc, char** argv) {
addergraph.init();
addergraph.run(4);
addergraph.end();
return 0;
}
#endif2.1.4. aie_graph.h
aie_graph.cpp定义了运算的graph，仿真和实际运行都需要。
代码语言：javascript复制#include <adf.h>
#include "aie_kernel.h"
using namespace adf;
class simpleGraph : public graph {
private:
kernel adder;
public:
port<input> in0, in1;
port<output> out;
simpleGraph() {
adder = kernel::create(aie_adder);
connect<stream>(in0, adder.in[0]);
connect<stream>(in1, adder.in[1]);
connect<stream>(adder.out[0], out);
source(adder) = "aie_adder.cc";
runtime<ratio>(adder) = 0.1;
};
};2.1.5. aie_kernel.h
aie_kernel.h最简单，只声明了aie_adder的原型，仿真和实际运行都需要。
代码语言：javascript复制void aie_adder(input_stream_int32* in0, input_stream_int32* in1, output_stream_int32* out);2.1.6. host.cpp
host.cpp会申请内存，加载数据, 加载xclbin, 运行AIE Kernel。
代码语言：javascript复制simpleGraph addergraph;
static std::vector<char> load_xclbin(xrtDeviceHandle device, const std::string& fnm) {
// load bit stream
std::ifstream stream(fnm);
stream.seekg(0, stream.end);
size_t size = stream.tellg();
stream.seekg(0, stream.beg);
std::vector<char> header(size);
stream.read(header.data(), size);
auto top = reinterpret_cast<const axlf*>(header.data());
xrtDeviceLoadXclbin(device, top);
return header;
}
int main(int argc, char** argv) {
// Open xclbin
auto dhdl = xrtDeviceOpen(0); // Open Device the local device
auto xclbin = load_xclbin(dhdl, "krnl_adder.xclbin");
auto top = reinterpret_cast<const axlf*>(xclbin.data());
adf::registerXRT(dhdl, top->m_header.uuid);
int DataInput0[sizeIn], DataInput1[sizeIn];
for (int i = 0; i < sizeIn; i ) {
DataInput0[i] = rand() % 100;
DataInput1[i] = rand() % 100;
}
// input memory
// Allocating the input size of sizeIn to MM2S
// This is using low-level XRT call xclAllocBO to allocate the memory
xrtBufferHandle in_bohdl0 = xrtBOAlloc(dhdl, sizeIn * sizeof(int), 0, 0);
auto in_bomapped0 = reinterpret_cast<uint32_t*>(xrtBOMap(in_bohdl0));
memcpy(in_bomapped0, DataInput0, sizeIn * sizeof(int));
printf("Input memory virtual addr 0x%pxn", in_bomapped0);
xrtBufferHandle in_bohdl1 = xrtBOAlloc(dhdl, sizeIn * sizeof(int), 0, 0);
auto in_bomapped1 = reinterpret_cast<uint32_t*>(xrtBOMap(in_bohdl1));
memcpy(in_bomapped1, DataInput1, sizeIn * sizeof(int));
printf("Input memory virtual addr 0x%pxn", in_bomapped1);
// output memory
// Allocating the output size of sizeOut to S2MM
// This is using low-level XRT call xclAllocBO to allocate the memory
xrtBufferHandle out_bohdl = xrtBOAlloc(dhdl, sizeOut * sizeof(int), 0, 0);
auto out_bomapped = reinterpret_cast<uint32_t*>(xrtBOMap(out_bohdl));
memset(out_bomapped, 0xABCDEF00, sizeOut * sizeof(int));
printf("Output memory virtual addr 0x%pxn", out_bomapped);
// mm2s ip
// Using the xrtPLKernelOpen function to manually control the PL Kernel
// that is outside of the AI Engine graph
xrtKernelHandle mm2s_khdl1 = xrtPLKernelOpen(dhdl, top->m_header.uuid, "pl_mm2s:{pl_mm2s_1}");
// Need to provide the kernel handle, and the argument order of the kernel arguments
// Here the in_bohdl is the input buffer, the nullptr is the streaming interface and must be null,
// lastly, the size of the data. This info can be found in the kernel definition.
xrtRunHandle mm2s_rhdl1 = xrtKernelRun(mm2s_khdl1, in_bohdl0, nullptr, sizeIn);
printf("run pl_mm2s_1n");
xrtKernelHandle mm2s_khdl2 = xrtPLKernelOpen(dhdl, top->m_header.uuid, "pl_mm2s:{pl_mm2s_2}");
xrtRunHandle mm2s_rhdl2 = xrtKernelRun(mm2s_khdl2, in_bohdl1, nullptr, sizeIn);
printf("run pl_mm2s_2n");
// s2mm ip
// Using the xrtPLKernelOpen function to manually control the PL Kernel
// that is outside of the AI Engine graph
xrtKernelHandle s2mm_khdl = xrtPLKernelOpen(dhdl, top->m_header.uuid, "pl_s2mm");
// Need to provide the kernel handle, and the argument order of the kernel arguments
// Here the out_bohdl is the output buffer, the nullptr is the streaming interface and must be null,
// lastly, the size of the data. This info can be found in the kernel definition.
xrtRunHandle s2mm_rhdl = xrtKernelRun(s2mm_khdl, out_bohdl, nullptr, sizeOut);
printf("run pl_s2mmn");
// graph execution for AIE
printf("graph init. This does nothing because CDO in boot PDI already configures AIE.n");
addergraph.init();
printf("graph runn");
addergraph.run(N_ITER);
addergraph.end();
printf("graph endn");
// wait for mm2s done
auto state = xrtRunWait(mm2s_rhdl1);
std::cout << "mm2s_1 completed with status(" << state << ")n";
xrtRunClose(mm2s_rhdl1);
xrtKernelClose(mm2s_khdl1);
state = xrtRunWait(mm2s_rhdl2);
std::cout << "mm2s_2 completed with status(" << state << ")n";
xrtRunClose(mm2s_rhdl2);
xrtKernelClose(mm2s_khdl2);
// wait for s2mm done
state = xrtRunWait(s2mm_rhdl);
std::cout << "s2mm completed with status(" << state << ")n";
xrtRunClose(s2mm_rhdl);
xrtKernelClose(s2mm_khdl);
// Comparing the execution data to the golden data
// clean up XRT
std::cout << "Releasing remaining XRT objects...n";
xrtBOFree(in_bohdl0);
xrtBOFree(in_bohdl1);
xrtBOFree(out_bohdl);
xrtDeviceClose(dhdl);
return errorCount;
}2.1.7. pl_mm2s.cpp
pl_mm2s.cpp是利用HLS做的PL设计，用于从内存搬移数据到AIE Kernel。
代码语言：javascript复制void pl_mm2s(ap_int<32>* mem, hls::stream<qdma_axis<32, 0, 0, 0> >& s, int size) {
data_mover:
for (int i = 0; i < size; i ) {
qdma_axis<32, 0, 0, 0> x;
x.data = mem[i];
x.keep_all();
s.write(x);
}
}2.1.8. pl_mm2s.cpp
pl_mm2s.cpp也是利用HLS做的PL设计，用于从AIE Kernel搬移数据到内存。
代码语言：javascript复制void pl_s2mm(ap_int<32>* mem, hls::stream<qdma_axis<32, 0, 0, 0> >& s, int size) {
data_mover:
for (int i = 0; i < size; i ) {
qdma_axis<32, 0, 0, 0> x = s.read();
mem[i] = x.data;
}
}2.2. 经验
AIE a2z 做得相当完善，基本可以顺利完成。 在实验过程中，可能遇到下列问题。
2.2.1. AXI Interrupt
创建平台（Platform）时，AXI中断控制器（axi_intc）没有连接中断源。Vitis编译工程时，会连接HLS设计的IP模块的中断输出到AXI中断控制器（axi_intc）。 如果验证平台（Platform）的Block Design时，Vivado会报告下列关于中断控制器消息，提示没有中断源，可以忽略。
代码语言：javascript复制[BD 41-759] The input pins (listed below) are either not connected or do not have a source port, and they don't have a tie-off specified. These pins are tied-off to all 0's to avoid error in Implementation flow.
Please check your design and connect them as needed:
/axi_intc_0/intr2.2.2. sys_clk0
Vivado也会对输入时钟报告下列时钟不匹配的消息。Vivado创建Block Design时，默认的时钟是100MHz。单板上的实际时钟是200MHz。选中sys_clk0_0，在属性中，把它更改为200MHz。
代码语言：javascript复制[xilinx.com:ip:axi_noc:1.0-1] /ps_nocClock frequency of the connected clock (/ps_noc/sys_clk0) is 100.000 MHz while "Input System Clock Frequency" is 200.000 MHz. Please either reconfigure the parameter "Input System Clock Period" of the axi_noc (in DDR Basic tab) or change frequency of the connected clock (CONFIG.FREQ_HZ) within the range of 199920031.987 to 200080032.013 Hz.2.2.3.
