A 167-processor computational platform consists of an array of simple programmable processors capable of per-processor dynamic supply voltage and clock frequency scaling, three algorithm-specific processors, and three 16 KB shared memories; and is implemented in 65 nm CMOS. All processors and shared memories are clocked by local fully independent,(More)
A 167-processor 65 nm computational platform well suited for DSP, communication, and multimedia workloads contains 164 programmable processors with dynamic supply voltage and dynamic clock frequency circuits, three algorithm-specific processors, and three 16 KB shared memories, all clocked by independent oscillators and connected by configurable(More)
The Asynchronous Array of Simple Processors (AsAP) uses processor cores with small instruction and data memories to dramatically reduce area and power while increasing performance. Fig. 23.6.1 shows the architecture of an individual AsAP processor and the 6×6 array contained on the chip. Data enters the array through the upper left processor and exits from(More)
An array of simple programmable processors is implemented in 0.18 m CMOS and contains 36 asynchronously clocked independent processors. Each processor occupies 0.66 mm and is fully functional at a clock rate of 520–540 MHz at 1.8 V and over 600 MHz at 2.0 V. Processors dissipate an average of 32 mW under typical conditions at 1.8 V and 475 MHz, and 2.4 mW(More)
This paper presents the architecture of an asynchronous array of simple processors (AsAP), and evaluates its key architectural features as well as its performance and energy efficiency. The AsAP processor calculates DSP applications with high energyefficiency, is capable of high-performance, is easily scalable, and is well-suited to future fabrication(More)
Long-QT syndrome (LQTS) is an arrhythmogenic disorder characterised by prolongation of the QT interval in the electrocardiogram, which can lead to sudden cardiac death. Pharmacological treatments are far from optimal for congenital forms of LQTS, while the acquired form, often triggered by drugs that (sometimes inadvertently) target the cardiac hERG(More)
This paper investigates the performance and power dissipation of globally asynchronous locally synchronous (GALS) multi-processor systems. We show that communication loops are a source of significant throughput degradation in communications links and that there is no degradation whatsoever under certain conditions for one-way links, and that it is possible(More)
