Cores¶

The following is a list of currently implemented cores.

FIFO¶

Various synchronous and asynchronous FIFO implementations.

fpgalink¶

This is a MyHDL implementation of the HDL for the fpgalink project. The fpgalink HDL core can be instantiated into a design:

For simulation and verification the fpgalink interface can be stimulated using the FX2 model and high-level access functions:

The following is a pictorial of the verification environment .

For more information on the [fpgalink]() software, firmware, and general design information see [makestuff]().

usbp¶

USB Peripheral, this is another Cypress FX2 controller interface, this has two interfaces a “control” interface and a “streaming” interface. This FX2 interface is intended to work with the [fx2 firmware]() that configures the controller as a USB CDC/ACM device (virtual serial port). The [fx2 firmware]() also has a couple vendor unique commands that can be sent using the pyusb (or other low-level USB interfaces like libusb). The Python version of the host software (including firmware) can be retrieved via pip

>> pip install usbp
>>> import usbp
>>> import serial

One of the tricky items with USB devices is setting the permissions correctly. On a linux system to set the …

spi¶

This is a generic SPI controller.

vga¶

VGA controller.
