Processor 草榴社区 for Network Attached Storage
Overview
Network attached storage (NAS) allows users to share storage over a common network. NAS typically requires a higher level of processing performance to handle increased data bandwidth from wired/wireless communication links as well as RAID data traffic to and from off-chip ASICs.
Highlights:
CPU
- High-performance ARC HS4x, HS5x for wired & wireless network communication (including WiFi)
- Single- and multi-core processors for networking apps & RAID management
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
- ARC EM4 and EM6 processors optimized for power & area
- Native support for DSP with ARC EMxD cores & Data Fusion Subsystem
- Tightly coupled communications MACs for lower latency, power
- Programmable accelerators (ASIP) for matrix, FFT, filtering
