MapleDSP System Generator Tool

Our MapleDSP tool is a versatile tool for generating signal processing structures on an FPGA in Verilog. Its front end consists of a powerful coefficient generation engine coupled with a graphical display to generate plots for studying magnitude and phase characteristics, which is coupled with a backend that uses a uses a novel templating technique to generate code modules that can be synthesized.

The front end generates the following coefficient types:

• Biquadratic IIR filters
• Windowed FIR filters
• CIC Interpolation/Decimation filters
• Sine/Cosine generator tables
• Raised Cosine filters
• Frequency sampling filters
• Custom coefficient filters
• Fast Fourier Transforms
• LMS Discreate Fourier Transform
• LSM Adaptive filters

The back end produces verilog code for the following FPGA types:

• Intel Max 10 Family
• Intel Cyclone V Family

Maple Pi HAT Products

The Maple Pi HAT is a test and evaluation platform that mounts on a raspberry Pi B or B+, and contains a MAX 10 FPGA with an audio codec, 8 channel A/D and RS232 interface. It can be programmed directly from the Pi or with a JTAG probe for debugging. There are three models available:

Model	Logic Gates	Suitability
MaplePI-08	8K	Small designs and proof of concept
MaplePI-25	25K	Designs with 1-5 DSP elements
MaplePI-50	50K	FFT's, Adaptive filters, more complex structures
