Resource Optimization of a Hardware Accelerator
Beschreibung
Modern compute architectures increasingly rely on heterogeneous systems that combine general-purpose CPUs with dedicated hardware accelerators. These accelerators offer significant performance benefits and reduce CPU load, but require efficient interfaces and notification mechanisms to be fully effective. A proof-of-concept for hardware-assisted task notification has already been implemented and evaluated in a full-system simulation using Gem5.
This work builds on the existing framework and focuses on improving a hardware prototyping environment to evaluate these concepts on a real platform. The target system is an Xilinx Zynq board that integrates ARM multicore processors with FPGA-based programmable logic and runs a Linux-based software stack.
The main objective is to optimize the resources of an existing hardware unit. This includes analyzing resource usage (e.g., LUTs, BRAM, DSPs) and performance, identifying inefficiencies, and applying optimizations at the RTL and system level. The optimized design will be implemented and evaluated on the FPGA, with results compared to the baseline.
Tasks include:
- Analyzing the existing hardware design and identifying bottlenecks
- Implementing and validating resource optimizations
- Testing on the FPGA platform and evaluating results
- Documenting the work and findings
Voraussetzungen
To successfully complete this work, you should have:
- first experience with embedded programming,
- very good programming skills in System Verilog,
- basic knowledge about Git,
- first experience with the Linux environment.
The student is expected to be highly motivated and independent.
