fpga_linear_time_sorter - a parallel sorting algorithm implemented in hardware that sorts data in linear time as it arrives serially

This algorithm is fast, since the sorting itself is done in parallel while the data is being input serially. It is sorted and ready to be read back immediately following the last write transfer.

A 256-length, 8-bit sorter costs approximately 5500 logical elements on an Altera Cyclone IV.

NNgen is an open-sourced compiler to synthesize a model-specific hardware accelerator for deep neural networks. NNgen generates a Verilog HDL source code and an IP-core package (IP-XACT) of a DNN accelerator from an input model definition.

Generated hardware is all-inclusive, which includes processing engine, on-chip memory, on-chip network, DMA controller, and control circuits. So the generated hardware does not require any additional controls from an external circuit or the CPU after the processing is started.

An FPGA-based 7-ENOB 600 MSample/s ADC without any External Components

In this work, a new structure of an FPGA-based ADC is proposed. The ADC is based on the slope ADC, where a time-to-digital converter (TDC) measures the time from the beginning of a reference slope until the slope reaches the voltage-to-be-measured.

Only FPGA-internal elements are used to build the ADC. It is fully reconfigurable and does not require any external components. This innovation offers the flexibility to convert almost any digital input/output (I/O) into an ADC.

The proposed ADC has a resolution of 9.3 bit and achieves an effective number of bits (ENOB) of 7 at a sample rate of 600 MSample/s. An alternative version of the ADC operates at 1.2 GSample/s and achieves an ENOB of 5.3.

USB_CDC - Full Speed (12Mbit/s) USB communications device class (or USB CDC class) for FPGA and ASIC designs.

USB_CDC implements the Abstract Control Model (ACM) subclass. Windows 10 provides a built-in driver (Usbser.sys) for USB CDC devices. A USB_CDC device is automatically recognized by Windows 10 as a virtual COM port, and a serial port terminal application such as CoolTerm can be used to communicate with it.

macOS and Linux provide built-in drivers for USB CDC ACM devices too. On macOS, the virtual COM gets a name like /dev/cu.usbmodem14601, whereas, on Linux, it gets a name like /dev/ttyACM0.
