Floating-point precisions

Range of floating-point precisions optimised for device features, thereby enabling users to choose the right trade-off of precision against hardware resources for their applications

Support for vector manipulation

Native support for vectors in a high level design flow is essential to enable "super-sample rate" designs, where the data rate is much higher than the FPGA clock rate, as the samples must be processed in parallel. The design tool has to provide not just vector data types, but the ability to manipulate vectors, vector sums, vector accumulation, vector dot product, vector cross products and so forth.

FFT processing

A 'super-sample' FFT processing 128 complex (real and imaginary) data samples per clock cycle
