LTE and LTE-A provide high data rates and need fast control. Talk to our FAE team about Cortex-R4 and the roadmap for modem processors. Small cores such as Cortex-M0, Cortex-M3 and ARM968E can provide additional flexible processing for Layer1 without increasing silicon cost. To keep system frequencies low, multiple controllers can be used and debugged using Coresight.
Highly efficient processors such as Cortex-R4 and ARM1156T2 can reduce frequency and enable use of low leakage cells and lower system voltage. By using advanced controllers, savings in power and die area can be made. Further improvements in power, performance and area, made in careful selection of cell library to balance the performance required with low leakage and minimum area memories and logic.Bluetooth & Zigbee
Cortex-M3 provides an excellent match to requirements for connectivity standards. The efficiency gains of a modern controller, using Thumb-2 and fast interrupt handling means reduced system frequencies with consequent reductions in power. Small code size assists in keeping costs down and in hosted systems, even smaller Cortex-M0 solutions are possible.
