Based on TI’s high-throughput KeyStone II architecture, the new TCI6630K2L system-onchip (SoC) is a scalable low-power baseband solution with an integrated digital radio front end (DRFE) that meets the more stringent power, size and bill of materials (BOM) cost requirements of small cell wireless base stations. In enterprise and pico base stations, the device’s dual ARM/quad DSP cores deliver t...

Service oriented applications feature interactions among several participants over the network. Mechanisms such as correlation sets and two-party sessions have been proposed in the literature to separate messages sent to different instances of the same service. This paper presents a process calculus featuring dynamically evolving multiparty sessions to model interactions that spread over severa...

This paper describes the methodology employed by the IBM Microelectronics Division for the design of its Blue Logic applicationspecific integrated circuits (ASICs) and system-on-a-chip (SoC) designs. This methodology is used by both IBM ASIC and SoC designers, as well as OEM customers. A key focus of the IBM ASIC/SoC methodology, outlined in the first section of this paper, is the first-time-ri...

The design of Low Power Systems-on-Chips (SoC) in very deep submicron technologies becomes a very complex task that has to bridge very high level system description with low-level considerations due to technology defaults and variations and increasing system and circuit complexity. This paper describes the major low-level issues, such as dynamic and static power consumption, temperature, techno...

A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it. It is a capital mistake to theorize before one has data. Is it SOC or not? asked Hendrik Jeldtoft Jensen in the final chapter of his book Self-Organized Criticality: Emergent Complex Behavior i...

SoC Architecture Explorer is an architecture exploration tool for SoC design. It explores all possible parameter sets under constraints and estimates design quality of every architecture candidates.

For a 1s electron, whose velocity is equal to Z in atomic units, the relativistic effect leading to heavier mass, for heavy elements (Z high), thus cannot be ignored. The result is a relativistic contraction of the orbitals, causing lowering of Zeff on orbitals of higher angular momentum. This calls for a relativistic treatment of quantum dynamics. For an equation of motion to hold in a relativ...

Communication design for SoCs poses the unique challenges in order to cover a wide range of architectures while offering new opportunities for optimizations based on the application specific nature of system designs. In this report, we propose automatic generation of communication topology from partitioned, scheduled architecture model where system components communicate through message passing...

Variation of soil organic carbon (SOC) and its major constraints in large spatial scale are critical for estimating global SOC inventory and projecting its future at environmental changes. By analyzing SOC and its environment at 210 sites in uncultivated land along a 3020km latitudinal transect in East Central Asia, we examined the effect of environmental factors on the dynamics of SOC. We foun...
