Embedded Systems Design Europe - February 2008 - (Page 28) feature Multicore architectures can provide the performance boost you’re looking for, but the software is certainly more complicated. Is symmetric multiprocessing BY DAVID N. KLEIDERMACHER or the past thirty years, computing has enjoyed continual boosts in performance, primarily due to increases in clock speed, pipelining efficiency, and cache size. Recently, however, traditional microprocessor optimization has hit the proverbial wall. Although tweaks such as further cache size increases can continue to nudge system performance, it’s clear that Moore’s gains are behind us. Meanwhile, embedded systems continue to grow in software complexity, with consumers expecting that all the bells and whistles will continue to come in ever shrinking cost, size, weight, and power footprints. Microprocessor designers have concluded that the best path toward meeting the growing demand for performance with controlled footprint is to employ multicore architectures, in which the main premise is to partition the software and parallelize or offload execution across multiple processing elements. Symmetric multiprocessing (SMP) is one such architecture, consisting of homogenous cores that are tightly coupled with a common memory subsystem, as shown in Figure 1. SMP is a de facto standard on the desktop, but adoption in embedded applications has been slow, with recent surveys showing only a small percentage of designs using single-chip SMP-capable devices.
