    Performance Enhancement for IPsec Processing on Multi-Core Systems

    Most of the existing crypto drivers cannot operate effectively over the multi-core systems, resulting in high synchronization overheads. Moreover, the crypto drivers under utilize the full capacity of the hardware device underneath, resulting in low IP-sec throughput. This paper discusses a design methodology that virtualizes the access to the common...

    Ethernet Jumbo Frames in SmartDSP OS Applications

    The maximum Ethernet frame size is defined as 1518 bytes in the IEEE 802.3 Ethernet standard. A specially defined Ethernet jumbo frame can be used to increase the Ethernet throughput and to reduce the CPU/DSP core load. Note that Ethernet jumbo frames are not defined in the IEEE 802.3 standard,...

    Hardware and Software Assists in Virtualization

    Until recently, embedded systems were often built with computing blocks containing a single CPU. Each block included a processor, memory controller and I/O bridge. This model has been a long-lived one. As applications demanded additional performance, Moore's Law delivered ever faster and more sophisticated processors and bridge silicon. In return,...

    Serial-to-Ethernet Bridge Using MCF51CN Family and FreeRTOS

    This paper describes a serial-to-Ethernet bridge using the MCF51CN128, the open-source RTOS FreeRTOS v5.3.0 and the TCP/IP stack LwIP v1.3.0. Serial interfaces used are UART and SPI. Ethernet connects using a well-known socket implementation. This paper was written to help you enable older serial interface-related designs for Ethernet connectivity. Microcontrollers...

    Green Embedded Computing and the MPC8536E PowerQUICC III Processor

    Growing energy demands from embedded electronics and increasing evidence of dramatic global climate change are generating greater environmental and cultural pressure for green solutions in embedded computing applications. This, coupled with continued expectations for higher performance embedded computing with each new product generation, despite environmental concerns, is impacting the future...

    Freescale Technologies for Energy Efficiency

    The design of an electronic system is almost always constrained by power and energy considerations - whether it is battery life for a mobile device, thermal power dissipation in a high-performance processor or ultra-low power consumption for a wireless sensing application. In addition, recent economic forces and increased environmental awareness...
