Matlab Based High Level Synthesis Engine for Area And Power Efficient Arithmetic Operations

Embedded systems used in real-time applications require low power, less area and a high computation speed. For digital signal processing (DSP), image processing and communication applications, data are often received at a continuously high rate. Embedded processors have to cope with this high data rate and process the incoming data based on specific application requirements. Even though there are many different application domains, they all require arithmetic operations that quickly compute the desired values using a larger range of operation, reconfigurable behavior, low power and high precision. The type of necessary arithmetic operations may vary greatly among different applications. The RTL-based design and verification of one or more of these functions may be time-consuming. Some High Level Synthesis tools reduce this design and verification time but may not be optimal or suitable for low power applications. The developed MATLAB-based Arithmetic Engine improves design time and reduces the verification process, but the key point is to use a unified design that combines some of the basic operations with more complex operations to reduce area and power consumption. The results indicate that using the Arithmetic Engine from a simple design to more complex systems can improve design time by reducing the verification time by up to 62%. The MATLAB-based Arithmetic Engine generates structural RTL code, a testbench, and gives the designers more control. The MATLAB-based design and verification engine uses optimized algorithms for better accuracy at a better throughput.
