Heterogeneous Computing Meets the Data Center

CATEGORIES : All, Bandwidth, Design Challenges/AUTHOR : Ron Wilson

As we push single-CPU performance deeper into diminishing returns and begin extracting the last big gains from multicore processors, computing experts are turning to another old idea—heterogeneous multiprocessing—as the next way to advance. In heterogeneous systems, different kinds of processors—x86 CPUs and FPGAs, for example—cooperate on a computing task. Heterogeneous architectures are already widely used […]

The Next-Generation Cellular Network Takes Shape

CATEGORIES : All, Design Challenges, System Architecture/AUTHOR : Ron Wilson

The global network supporting mobile devices is facing profound challenges to its architecture and to its underlying technology. Driven by cell phones’ own spectacular success, the number of mobile client devices and their individual appetites for bandwidth keep growing. But the bandwidth allocated to the mobile carriers is not increasing at anything approaching the same […]

Big Data: Where It Comes From, Where It Will Go

CATEGORIES : All, Design Challenges, System Architecture/AUTHOR : Ron Wilson

The near future will see massive growth in mobile computing, in network traffic, and in the sheer size of data sets. These are all familiar trends, but often they are stated without reference to specifics. Even less often do discussions of these trends include mention of the impact they will have on hardware in the […]

Attaching Accelerators in Multicore Systems

CATEGORIES : All/AUTHOR : Ron Wilson

We have entered the age of heterogeneous multiprocessing. In high-performance computing applications, architects are adding hardware accelerators to the multicore CPU clusters in their huge supercomputers. At the other end of the spectrum, designers of embedded and mobile systems are moving critical code loops into hardware to slash energy consumption. Everywhere in between, embedded-system designers […]

Altera’s 30th Anniversary: Looking Forward

CATEGORIES : All, Design Challenges, System Architecture/AUTHOR : Ron Wilson

As Altera enters its fourth decade, there seems to be little agreement among experts about the future of programmable logic. Some argue that spiraling SoC development cost and shrinking product cycles are making the two obvious alternatives to FPGAs – ASICs and ASSPs – untenable, opening the door to a much wider market for programmable […]
