Kahn Process Network: Parallel Programming Without Races And Non-Determinism


Modern personal computing devices feature multiple cores. This is not only true for desktops, laptops, tablets and smartphones, but also for small embedded devices like the Raspberry Pi. In order to exploit the computational power of those platforms, application programmers are forced to write their code in a parallel way. Most often, they use the threading approach. This means multiple parts o... » read more

Accelerating Financial Applications With SLX FPGA


This white paper demonstrates how engineers creating FPGA-based hardware accelerators for financial market models can take advantage of SLX FPGA. SLX FPGA can be used to accelerate optimization efforts for financial market models targeting option pricing. In this paper, two implementations of computation intensive models for pricing options are discussed, namely the Black-Scholes and Heston pri... » read more

Using SLX FPGA For Performance Optimization Of SHA-3 For HLS


Author: Zubair Wadood SLX FPGA facilitates converting your C/C++ project into an FPGA bitstream easier and with higher performance. Leveraging standard HLS (High Level Synthesis) tools from FPGA vendors, SLX FPGA tackles the challenges associated with the HLS design flow. In this paper, the results of an SLX FPGA-optimized implementation of a Secure Hash Algorithm (SHA-3; also known as Kecca... » read more

Pushing Performance: Analysis and Optimization of Multicore Communication with SLX


In theory, multicore programming should be simple: Tasks are placed on available cores and allocated a data buffer in the shared memory to communicate data between two tasks. However, the amount of communication resources in the latest multicore SoC is very limited. One cannot deal with all the data communications required by all the tasks without being able to understand communication conte... » read more

Multicore Software Design For An LTE Base Station


This paper presents a typical base station design scenario, where decisions about HW/SW partitioning, the number of processing elements, and operational system parameters, among other things, need to be made early on by system architects. SLX determines the impact of these various design decisions and parameter selections, while exploring different target architecture configurations and checks ... » read more

How Many Cores? (Part 2)


New chip architectures and new packaging options—including fan-outs and 2.5D—are changing basic design considerations for how many cores are needed, what they are used for, and how to solve some increasingly troublesome bottlenecks. As reported in part one, just adding more cores doesn't necessarily improve performance, and adding the wrong size or kinds of cores wastes power. That has s... » read more
