How to Choose a CPU for your SoC Design Product News 12/17/2003 Post a comment The one element that can make or break a design is the CPU. If you consider that the CPU is to the system-on-chip (SoC) what an engine is to an automobile, then you know you wouldn't put a Ferrari engine into a Hummer and expect it
to perform. Although the
Ferrari may deliver similar horsepower to the Hummer engine, it would fail due
to a lack of torque. Simple assessments of horsepower are just as misleading in CPU selection as they are in the automobile world.
Portability Fueling 32-bit Expansion Product News 12/16/2003 Post a comment The 32-bit architecture was once thought of as only for high-end,
processor-intensive applications, but that is changing. Demand for more
sophistication, features and performance in a variety of portable electronic
devices is the driving force causing designers to consider a switch from using
8-/16-bit to 32-bit microcontrollers in their designs.
Taking the 32-bit Plunge Promises Payoffs Product News 12/16/2003 Post a comment What specific factors are fueling the shift from
8- to 32-bit architectures? One is the growing need for a broader addressing range. Many 8-bit architectures today are limited to 64k of addressing range.
Some microcontroller families are unable to address external program memory,
thus limiting the address range to whatever memory is implemented on the chip. A
few 8-bit architectures are able to address up to a few megabytes of off-chip
memory, and in some cases, extended address range is ac
Design your op amps online Product News 12/16/2003 Post a comment National Semiconductor Corporation announced its Amplifiers Made Simple tool, the industry's first online design tool created to speed the selection, design and testing of many types of operational amplifiers.
Reset Chips for Microprocessor Apps Product News 12/15/2003 Post a comment STMicroelectronics on Monday (Dec. 15) announced four new microprocessor Reset chips intended for high volume microprocessor-based applications, including computers, servers, printers, fax machines, cellular and GSM phones, and consumer products. Reset circuits are supervisory devices that are commonly used to monitor the microprocessor supply voltage, and to generate a reset signal if that voltage falls below tolerance.
Video decoder/de-interlacer solution for LCD displays Product News 12/15/2003 Post a comment Royal Philips Electronics introduced its SAA7154 single chip system solution - a video decoder, scaler and de-interlacer with picture improvements and memory less Edge Dependant De-Interlacing (EDDI) and LCD controller for use in Liquid Crystal Display (LCD) TV's, LCD monitors.
TI upgrades applications processor for high-end cell phones Product News 12/15/2003 Post a comment Texas Instruments is readying its next generation OMAP DSP-based applications processor for high-end multimedia smartphones phones that will deliver an improvement in speed, while consuming significantly less power than its current application processors, thanks to the use of TI's 90 nanometer (0.09 micron) process technology.
PC Refresh News & Analysis 12/12/2003 Post a comment Who's the comeback player of the year in technology? The PC. While the consumer PC market is growing again, the corporate computer upgrade cycle has begun after a long drought, said Brian Fravel, director of desktop marketing at Intel Corp.
Over-voltage protection IC responds in a flash Product News 12/12/2003 Post a comment ON Semiconductor's NCP346 is an over-voltage protection circuit (OVP) optimized for applications with an external AC/DC adapter, car charger accessory or a battery charger. The NCP346 will protect battery chargers from high input-voltage events (up to 30-volt transients) by quickly disconnecting the charger from the adapter, responding to turn off a series PFET in less than 1 microsecond.
3-in-1 regulator shrinks DDR power solutions Product News 12/12/2003 Post a comment California Micro Devices bills its CM3131 family as the industry's first fully integrated, all-linear DDR voltage regulator solution for cost-sensitive PC and consumer set-top applications. These regulators provide VDDQ, VTT and VSTBY power for DDR and DDR II SDRAM memories. The CM3131, according to the company, differs from existing switching regulator based solutions by doing away with the need for multiple external FETs and inductors, thus cutting solution costs by up to 70 percent and board
