Stream Board

Stream is a flexible platform for developing high-performance digital and RF designs using an Altera Cyclone IV FPGA and Lime Microsystems FPRF transceiver. The board incorporates SDRAM, Micro SD storage and a selection of other useful peripherals, with expansion via RFDIO and FMC mezzanine cards enabling use with both Myriad-RF 1 and LMS7002M EVB RF modules.

An OpenRISC SoC is available for Stream that is capable of running Linux and bare metal applications, complete with a peripheral  controller for interfacing RFDIO cards such as Myriad-RF 1. This allows for a mixed development model whereby programming and control is done via a flexible RISC processor, with baseband processing taking place directly in the FPGA fabric.

Software is provided for use with the LMS7002M EVB that allows control of the transceiver, ADC spectrum to be analysed via an FFT viewer, and example waveforms to be loaded into the FPGA.
