High performance vector dsp for 4G applications
IP licensing specialist CEVA has launched the CEVA-XC323, described as the first high performance vector dsp for 4G wireless infrastructure applications.
The CEVA-XC323 delivers up to 4x performance improvement in wireless infrastructure applications compared to vliw dsps, while reducing the bill of materials by reducing the number of processors and hardware accelerators required.
Gideon Wertheizer, CEVA's ceo, said: "The CEVA-XC323 DSP is a 'game changer' in the 4G wireless infrastructure space and represents an important milestone in CEVA's evolutionary growth strategy beyond our stronghold of the wireless terminal market.
"Incumbent infrastructure dsp vendors have relied upon an inefficient combination of traditional vliw dsp architectures and hardware blocks to compensate for the lack of dsp performance. This results in complicated software design, limited platform reuse across different products, and essentially locks the oem to the dsp supplier."
The CEVA-XC323 integrates two high precision vector communication units designed specifically to cope with the processing load found in basestations, while supporting homogenous multicore designs commonly used in modern infrastructure architectures. The core incorporates support for wireless infrastructure control plane processing, typically handled by separate processors.
