OH! Open Hardware for Chip Designers
OH! is an open-source library of hardware building blocks based on silicon proven design practices at 0.35um to 28nm. The library is being used by Adapteva in desgning its next generation ASIC.
The library is written in standard Verilog (2005) and contains over 25,000 lines of Verilog code, over 150 separate modules. Examplse of functionality include: FIFOs, SPI (master/slave), GPIO, high speed links, memories, clock circuits, synchronization primitives,interupt controller, DMA.
