The ConnX DSP, from Tensilica, is a family of high-performance communications DSP (digital signal processors) IP (intellectual property) cores. The ConnX DSPs feature standard cores, click-box configurable options or a starting point for customized Xtensa® LX DPUs (dataplane processor units) for SOC (system-on-chip) designs. The new pre-designed communications DSP cores enables designers to achieve faster time-to-market on next-generation of communications SOCs.
There are two very different types of requirements for DSPs in wireless systems. The ConnX Baseband Engine fills the more traditional software-centric DSP requirements for base stations, and for multi-mode, multi-standard terminal devices. Tensilica’s Xtensa technology can also be optimized to build more narrowly tailored, optimized functional blocks that fit into a hardware-centric design style typically found in wireless handset implementations, and Tensilica plans several products in this area.
The ConnX family of communications DSP engines includes other functions that are in high demand for next-generation compute-intensive tasks. The ConnX Baseband Engine joins the proven quad-MAC Vectra LX DSP option, which is now re-branded as the ConnX Vectra Engine. The ConnX Vectra Engine has been used in many designs and is an integral part of the re-branded ConnX 545CK standard DSP. The ConnX 545CK was previously known as the Diamond 545CK, which received a BDTIsimMark2000 score of 3820. The BDTIsimMark is a summary measure of overall DSP processing speed based on BDTI’s DSP Kernel Benchmarks, and the 545CK received the highest BDTIsimMark2000 score of all licensable cores evaluated by BDTI. The ConnX family of DSP engines includes other functions that are in high demand for next-generation compute-intensive tasks.
