# Low-cost modular acquisition and stimulation system for neuroscience

This is a complete acquisition and stimulation system for timestamp-driven

neuroscience and neuroethology experiments. This system captures the instant

of occurrence of spikes and sends them to a computer through a USB JTAG-UART

interface. The computer also enqueues stimuli samples to be converted

by an DAC synchronously to the first acquisition channel.

The system is physically composed by the following components:

 * Altera MAX II CPLD (e.g. EPM2210)

 * Digital buffer for input protection (e.g. 74HC4050)

 * MAX5134 DAC

 * 32K x 8-bit SRAM (e.g. IDT71256)

More information is available in our [paper](http://arxiv.org/abs/1504.01718).

## Compiling and synthesizing

### Preparing

Edit `config.mk` and check if the Quartus II and Bluespec compiler paths

are correct. You may also pass these paths as environment variables.

### Compiling the software

    cd software && make

### Synthesizing one of the designs

    cd src/dynamic-arb && make

or

    cd src/static-arb && make
