Bristol firm ClearSpeed has won a £427,800 DTI grant to begin development of a 64-bit version of its multi-threaded parallel...

Designers using general purpose 8-bit microcontrollers for motor control applications may switch to 16- and even 32-bit devices...

Peripherals such as infrared (IR) and CAN bus interfaces and sensorless motor control circuitry are adding to the feature sets of that low-cost workhorse, the 8-bit microcontroller. Zilog has introduced a new Z8 one-time programmable (OTP) IR microcontroller targeted at universal remote control applications. Based on the Z8 core and built around Cisc architecture, the Crimzon ZLP32300 is intended for ...

For debugging embedded microcontrollers running at 200MHz speeds tool vendors are making use of high speed serial interfaces such as USB to speed up data transfers. But the Nexus high speed interface has become an established debug tool for high speed MCUs. Embedded software tools firm Crossware has developed a debugger for Motorola’s ColdFire family of processors that makes use ...

Freescale Semiconductor, the newly named Motorola semiconductor business, has given details of its latest PowerPC processor cores intended for system-on-chip design in communications and consumer applications. The mid-range e300 core is an upgraded version of the 603e PowerPC core used in previous-generation PowerQUICC II processors that scales from 266 to 667MHz in 130nm process technology. The enhanced core includes a ...
