Assignment 1
Developing a Custom Personality
- 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?
- Evaluate Hardware Options
- Define Custom Instructions
The functions implemented by the hardware design can then be mapped to custom instructions.
- 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
