ARM Cortex Application Processors? ?Cortex?-A?Series?- High performance processors for open Operating Systems Cortex Application Processors deliver?exceptional performance of?up to 2GHz+ typical frequency in advanced process nodes,?enabling the next generation of mobile internet devices.?The processors are available in single-core and multi-core varieties, delivering up to four processing units with optional?NEON? multimedia processing blocks and?advanced Floating Point execution units. Applications include? Smartphones Smartbooks Netbooks eBook Readers Digital TV Home Gateways Huge array of additional products ?ARM Specialist Processors SecurCore??- Processors for high security applications FPGA Cores?- Processors for FPGA ARM Specialist Processors are designed to meet the demanding needs of specific markets. SecurCore processors are utilized within the security markets for mobile SIMs and identification applications and integrate?numerous technologies to detect and avoid security attacks while?delivering outstanding performance. ARM also develops processors for FPGA fabrics, enabling users to rapidly reach market while maintaining compatibility with traditional ARM devices. Additionally the fabric independent?nature of these processors enables developers to choose the target device which is right for their application rather than be locked to a specific vendor. SecurCore applications include: SIMs Smart Cards?
