-AOCL Backend Example
-====================
-
-TVM supports Intel FPGA SDK for OpenCL also known as AOCL. Here is a tutorial for how to use TVM with AOCL.
-
-***Note***: This feature is still experimental. We cannot use AOCL to deploy an end to end neural networks for now. In addition, we only tested compilation for emulation mode of AOCL.
-
-We use two python scripts for this tutorial.
-
-- build.py - a script to synthesize FPGA bitstream.
-```
-import tvm
-from tvm import te
-tgt_host="llvm"
-tgt="aocl_sw_emu"
-
-n = te.var("n")
-A = te.placeholder((n,), name='A')
-B = te.placeholder((n,), name='B')
-C = te.compute(A.shape, lambda i: A[i] + B[i], name="C")
-
-s = te.create_schedule(C.op)
-px, x = s[C].split(C.op.axis[0], nparts=1)
-
-s[C].bind(px, tvm.thread_axis("pipeline"))
-
-fadd = tvm.build(s, [A, B, C], tgt, target_host=tgt_host, name="myadd")
-
-fadd.save("myadd.o")
-fadd.imported_modules[0].save("myadd.aocx")
-
-tvm.contrib.cc.create_shared("myadd.so", ["myadd.o"])
-```
-
-- run.py - a script to use FPGA as an accelerator.
-```
-import tvm
-import numpy as np
-import os
-
-tgt="aocl_sw_emu"
-
-fadd = tvm.runtime.load("myadd.so")
-fadd_dev = tvm.runtime.load("myadd.aocx")
-fadd.import_module(fadd_dev)
-
-ctx = tvm.context(tgt, 0)
-
-n = 1024
-a = tvm.nd.array(np.random.uniform(size=n).astype("float32"), ctx)
-b = tvm.nd.array(np.random.uniform(size=n).astype("float32"), ctx)
-c = tvm.nd.array(np.zeros(n, dtype="float32"), ctx)
-
-fadd(a, b, c)
-tvm.testing.assert_allclose(c.asnumpy(), a.asnumpy() + b.asnumpy())
-```
-
-Setup
------
-
-- Install AOCL 17.1 on Ubuntu 16.04.4 LTS.
-- Install BSP for your FPGA device.
-- Install FPGA device driver.
-- Create an ICD file at /etc/OpenCL/vendors/Altera.icd so that the OpenCL platform can be found.
-```
-/opt/intelFPGA/17.1/hld/linux64/lib/libalteracl.so
-```
-- Create an FCD file for example at /opt/Intel/OpenCL/Boards/s5_ref.fcd so that your FPGA device can be found.
-```
-/opt/intelFPGA/17.1/hld/board/s5_ref/linux64/lib/libaltera_s5_ref_mmd.so
-```
-- Setup TVM with AOCL and OpenCL enabled.
-
-Emulation
----------
-
-- Run software emulation
-```
-export CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA=1
-
-python build.py
-python run.py
-```
-
-- Run on FPGA devices (not tested)
- - Change tgt value to "aocl -device=s5_ref" on build.py and run.py
-```
-unset CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA
-
-python build.py
-python run.py
-```

-HLS Backend Example
-===================
-
-TVM supports Xilinx FPGA board with SDAccel. Here is a tutorial for how to deploy TVM to AWS F1 FPGA instance.
-
-***Note***: This feature is still experimental. We cannot use SDAccel to deploy an end to end neural networks for now.
-
-We use two python scripts for this tutorial.
-
-- build.py - a script to synthesize FPGA bitstream.
-```python

-
-fadd(a, b, c)
-tvm.testing.assert_allclose(c.asnumpy(), a.asnumpy() + b.asnumpy())
-```
-
-Setup
------
-
-- Launch an instance using the FPGA Developer AMI. We don't need an F1 instance for emulation and synthesis, so it is recommended to use a lower cost instance for them.
-
-- Setup AWS FPGA development kit.
-```bash
-git clone https://github.com/aws/aws-fpga.git
-cd aws-fpga
-source sdaccel_setup.sh
-source ${XILINX_SDX}/settings64.sh
-```
-
-- Setup TVM with OpenCL enabled.
-
-Emulation
----------
-
-- Create emconfig.json for emulation.
-```bash
-emconfigutil --platform ${AWS_PLATFORM} --nd 1
-```
-
-- Copy emconfig.json to the python binary directory. It is because the current Xilinx toolkit assumes that both host binary and the emconfig.json file are in the same path.
-```bash
-cp emconfig.json $(dirname $(which python))
-```
-
-- Run software emulation
-```bash
-export XCL_EMULATION_MODE=1
-export XCL_TARGET=sw_emu
-
-python build.py
-python run.py
-```
-
-- Run hardware emulation
-```bash
-export XCL_EMULATION_MODE=1
-export XCL_TARGET=hw_emu
-
-python build.py
-python run.py
-```
-
-
-Synthesis
----------
-
-- Run synthesis with the following script.
-
-```bash
-unset XCL_EMULATION_MODE
-export XCL_TARGET=hw
-
-python build.py
-```
-
-- Create AWS FPGA image and upload it to AWS S3.
-```
-${SDACCEL_DIR}/tools/create_sdaccel_afi.sh -xclbin=myadd.xclbin -o=myadd \
- -s3_bucket=<bucket-name> -s3_dcp_key=<dcp-folder-name> -s3_logs_key=<logs-folder-name>
-```
-This also generates an awsxclbin file, which is necessary to use the AWS FPGA image on F1 instances.
-
-Run
----
-
-- Launch Amazon EC2 F1 instance.
-
-- Copy `myadd.so`, `myadd.awsxclbin`, and `run.py` to the F1 instance.
-
-- Setup AWS FPGA development kit.
-```bash
-git clone https://github.com/aws/aws-fpga.git
-cd aws-fpga
-source sdaccel_setup.sh
-```
-
-- Setup TVM with OpenCL enabled.
-
-- Become root and setup environment variables.
-```bash
-sudo sh

-```bash
