The RJK0383DPA is a dual type power MOSFET allows fewer higher efficiency synchronous rectification DC / DC converters for the production of various strains on the supply of communications equipment and laptop computers. Improving the efficiency of electricity RJK0383DPA has two main advantages. It uses a small WPAK3 package, which reduces the chip mounting area to about half of the dual-package power MOSFET configuration, and offers the same power supply efficiency. In addition, the device allows to deliver more output current. High power MOSFET side has RJK0383DPA drain gate charge (Qgd) only 1.5nC (at VDD = 10V) for a rapid transition to high speed and efficiency. The device’s with low power MOSFET party is low on-resistance (RDS (on)), in 3.7mO (typical, at 4,5 V), which reduces the loss of power…

The ARM compiler helped the i.MX31 achieve up to a 2x increase in performance with one benchmark, and a 43 per cent increase in overall performance with all four benchmarks over an earlier version of the GCC compiler. These new benchmark scores demonstrate the benefits of ensuring that developers take advantage of the latest in compiler optimizations and technologies. Freescale’s i.MX31 processor, with a vector floating point coprocessor and L2 cache, is designed for wireless devices, such as portable media players and portable navigation devices, running computationally intensive multimedia applications…

EEMBC Publishes New Certified Scores for Freescale i.MX31 with ARM Compiler

New results show up to 2x performance increase

The Embedded Microprocessor Benchmark Consortium (EEMBC) announced the publication of new certified benchmark scores for the ARM processor-based Freescale i.MX31 multimedia applications processor. Tested with the ARM® RealView® RVCT 3.1 build 559 compiler, the new results supersede a previous set of certified scores using a GCC version 3.43 compiler and limited –O2 optimizations.

The VMDRIVE include rotating media options as well as several larger capacity solid-state storage options. Designed to meet demanding military and aerospace applications, the VMDRIVE enables deployment of recording applications in rugged conduction-cooled or commercial air-cooled environments. The rotating media VMDRIVE offers 300GB or 450GB storage capacity. This dual-slot VME or cPCI alternative is available in commercial air-cooled models. The VMDRIVE rotating media version stores data at 100 MB/s via dual channels of 2Gbps Fibre Channel…

VMDRIVE increases capacity and media options

VMETRO, a leader in high-speed data recording systems and rugged storage devices, announced the availability of additional new storage alternatives for its VMDRIVE. Available since January 2007, the VMDRIVE 6U VME/cPCI slot storage products now include rotating media options as well as several larger capacity solid-state storage options. Designed to meet demanding military and aerospace applications, the VMDRIVE enables deployment of recording applications in rugged conduction-cooled or commercial air-cooled environments.
