Processor 草榴社区 for Residential Gateways
Overview
The simple internet router is a thing of the past. Residential gateways have also become hubs for integrating media content, home security, VoIP, and smart energy. To manage all of this content, the embedded processors within these gateways must handle wired/wireless access, security protocols, and power management. DesignWare high-performance single-core and multicore CPUs provide power-efficient processing for these gateway applications.
Highlights:
CPU
- High-performance ARC HS4x, HS5x for network communication processing (including WiFi and BLE)
- Multi-core ARC HS processors manage communication links & services
Power Management IC
- Power- and area-efficient ARC EM4 for state machine calculations
- Sensor & Control Subsystem integrates control & register interfaces such as ADC interface for battery monitoring
SD Card
- ARC EM4 for power-critical, bus-powered apps like SD cards
- Best-in-class code density reduces memory size & power
- Fast interrupts and multiple register files for real-time response
- Custom instruction extensions to add differentiating HW
WiFi 802.11x Transceiver
- Tightly coupled communications MACs for lower latency, power
- Programmable accelerators (ASIP) for matrix, FFT, filtering
