Tensilica Releases ConnX Baseband Engine

Tensilica has brought out the ConnX DSP range of high-performance communications DSP (digital signal processors) IP (intellectual property) cores. The range includes standard cores, click-box configurable options or a starting point for customised Xtensa LX DPUs (dataplane processor units) for SOC (system-on-chip) designs. The latest addition to the range, the ConnX Baseband Engine, provides sixteen 18-bit MACs per cycle computational throughput, because of its application-specific instruction set optimised for compute-intensive LTE (long-term evolution) and 4G wireless base stations.

Tensilica plans other ConnX family members for the low-power requirements of the handset market. Will Strauss, president of Forward Concepts, said: 'With its configurable instruction set, Tensilica has morphed its basic Xtensa RISC architecture to become a compelling DSP engine.' Jack Guedj, president and chief executive officer of Tensilica, said: 'With this family of pre-designed communications DSP cores, our customers will be able to achieve faster time-to-market on their new next-generation of communications SOCs.' There are two different types of requirements for DSPs in wireless systems.

The ConnX Baseband Engine fills the more traditional software-centric DSP requirements for base stations and for multi-mode, multi-standard terminal devices. Tensilica's Xtensa technology can also be optimised to build more narrowly tailored, optimised functional blocks that fit into a hardware-centric design style typically found in wireless-handset implementations. Tensilica plans several products in this area. The ConnX range of communications DSP engines includes other functions that are in high demand for next-generation compute-intensive tasks.

The ConnX Baseband Engine joins the proven quad-MAC Vectra LX DSP option, which is now re-branded as the ConnX Vectra Engine. The ConnX Vectra Engine has been used in many customer designs and is an integral part of the re-branded ConnX 545CK standard DSP. The ConnX 545CK was previously known as the Diamond 545CK, which received a BDTIsimmark2000 score of 3820. The BDTIsimmark is a summary measure of overall DSP processing speed based on BDTI's DSP Kernel Benchmarks. The ConnX range of DSP engines includes other functions that are in high demand for next-generation compute-intensive tasks. Tensilica can quickly leverage its customisable processor technology to develop key functions that will significantly expand its business in several market areas.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
