Core architecture is optimised for comms
With a new type of processor architecture, Coresonic has developed a programmable baseband it reckons will revolutionise the communication industry.
Low-cost FPGA family available in production

Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
This personality pack is the first of a number of complete hardware packages that Coresonic will be developing - others will be announced for LTE, mobile media, short range communications, high speed short range communications, as well as legacy cellular systems.
According to Rick Clucas, CEO of Coresonic: "We have already spoken to a number of semiconductor companies and the main feedback we are receiving from them is that no other licensable solution appears to come close to our solution in terms of size and power consumption - in fact, some instruction caches are as large as our complete baseband processor solution".
He adds: "Recently a number of companies have made announcements in the market of WiMAX/DVB-T or DVB-T/H solutions, that we estimate are approximately 4-10x the size of our solution".
Commenting on the market challenge for programmable baseband processors, Clucas says: "OEMs are looking for a complete product which is low power and low cost - not lots of power hungry chips".
"The IP business model that we have chosen together with the personality packs for different standards is the only way that we believe this challenge can be met rapidly and efficiently".
Coresonic's WiMAX personality pack supports the mobile WiMAX 802.16e-2005 mobile system profile rev 1.4, which will support other modes such as 802.16d and 802.16j.
The pack performs everything from ADC/DAC interface to FEC, including digital front-end signal conditioning, synchronisation, MIMO channel estimation/compensation, error correction and chase combing.
All blocks provided enable a complete solution from the RF interface to interfacing to a CPU (central processor) to run the MAC layer; the processing intensive elements are implemented in hardware to minimise the load on the MAC CPU.
