Using Multicore Processors To Accelerate Your High-Performance Embedded Linux Applications


The adoption of Linux is accelerating, as it is becoming the operating system of choice for a variety of embedded applications. However, designers of these performance-intensive, embedded SoCs running Linux or other virtual-memory operating systems are challenged with increasing performance requirements within constant or shrinking power budgets. Most processors either achieve the performance g... » read more

How Reliable Is Your IP?


Almost everyone who has bought a new smartphone, car, home electronics device or appliance either has experienced technical glitches that require a replacement or repair, or they know someone who has experienced these problems. The good news is that only a very small fraction of the electronic glitches or failures can be contributed to hardware design. Most of it is due to manufacturing vari... » read more

Tackling Verification Challenges With Interconnect Validation Tool


An interconnect, also referred to as a bus matrix or fabric, serves as the communication hub of multiple intellectual property (IP) cores inside a system on chip (SoC). As the capacity of today’s SoCs continues to increase dramatically, interconnect verification complexity also grows, considering the master/slave numbers, various protocols, different kinds of transactions, and multi-layered t... » read more

SMP, Asymmetric Multi- processing And The HSA Foundation


When we hear the term “multiprocessing,” we often associate it with “symmetric multiprocessing (SMP).” This is because of SMP’s initial prevalence in the high-performance computing world, and now in x86/x64 servers and PCs. However, it’s been known for years that SMP’s ability to scale performance as the number of cores increases is poor. (For more information on SMP’s inability... » read more

The New Multicore Approach


It’s probably too harsh to say that multicore has been a failure, but it’s flat-out wrong to say it has been successful. Multicore was an inevitable outgrowth of Moore’s Law. You simply can’t keep turning up the frequency for processors at advanced nodes without cooking the chip into oblivion. In theory, four cores running at a much cooler 1GHz should be better than one core running... » read more
