Assignment 1

Developing a Custom Personality

1 Analyze Application

• How does the current application perform on existing hardware?
• What bottleneacks are limiting the performance?
• What data structures are involved?
• How parallelizable is the application?

2 Evaluate Hardware Options 3 Define Custom Instructions

• The functions implemented by the hardware design can then be mapped to custom instructions.

4 Develop Software Model of Custom Personality

• Convey provides an architecture simulation environment to allow rapid prototyping of both the hardware and software components of a custom personality.
• This environment is written in C++ to emulate the rest of the system. It includes hardware models of instruction dispatch, register state and the memory subsystem.

Running the Sample Application []

1. Copy Sample AE and Sample Application The Vadd sample personality and application is installed with the PDK RPM in /opt/convey/pdk/2010_08_09/.

The sample is made up of two components:

• cae_pers_vadd - contains the sample custom personality, including the software model which emulates the Application Engine FPGA
• SampleAppVadd - contains the application that uses the instruction defined in the CasSample tree.

cd $HOME
mkdir pdk_sample
cp -r /opt/convey/pdk/2010_08_09/cae_sample_vadd pdk_sample
cp -r /opt/convey/pdk/2010_08_09/pdk_apps/SampleAppVadd pdk_sample

2. Build the Sample AE and Sample Application

cd $HOME/pdk_sample/cae_pers_vadd/CaeSim
make
cd ../../SampleAppVadd
make
./UserApp.exe
