The three DSP block modes available are as follows:
In Arria 10 devices, Intel has enhanced the variable-precision DSP block by including hardened floating-point operators. The Arria 10 FPGA and SoC variable-precision DSP block introduces a new floating-point mode that delivers breakthrough floating-point performance of up to 1.5 TeraFLOPs.
The architectural innovation in the implementation of IEEE 754 single-precision hardened floating-point DSP (digital signal processing) blocks in Arria® 10 FPGAs and SoCs enable processing rates up to 1.5 TFLOPs (Tera Floating-point Operations Per Second) and power efficiency up to 40 GFLOPs/Watt.
With the three modes available for Arria® 10 DSP blocks: standard-precision fixed-point, high-precision fixed point and single-precision floating-point, designers can implement a variety of algorithms that require fixed point all the way to double-precision IEEE 754 compliant floating-point operations. Hardened floating-point processing offers designers the ability to implement algorithms in floating point with the similar performance and power efficiency as fixed point. This can be achieved without any power, area, or density compromises and with no loss of fixed-point features or functionality.
Arria 10 FPGAs and SoCs are a compelling solution for industrial, wireless systems, compute intensive applications such as high performance computing, machine learning, high-precision radars and data center acceleration applications.
A single DSP block in the floating-point mode provides an IEEE 754 single-precision floating-point multiplier and an IEEE 754 single-precision adder, delivering the highest floating-point performance on any FPGA in the market. These floating-point operators allow floating-point designs to be similar to traditional fixed-point designs, providing the benefits of floating-point at no additional cost for FPGA designers. Also, designers are able to remain in floating point, eliminating months of converting algorithms to fixed point and verifying the accuracy.
The floating-point mode offers:
In addition to floating-point capabilities, the new variable prevision block includes:
All DSP block modes feature a 64 bit accumulator and each variable-precision DSP block comes with a 64 bit cascade bus. The cascade bus allows the implementation of even higher precision signal processing through cascading multiple blocks using a dedicated bus.
The variable-precision DSP architecture maintains backward compatibility. It can efficiently support existing 18 bit DSP applications, such as high-definition video processing, digital up- or down- conversion and multirate filtering.
