DATASHEET
BA6289 描述
The unified program and data memory space of the ADSP-21991 consists of 16M locations that are accessible through two 24-bit address buses, the PMA, and DMA buses. The DSP uses slightly different mechanisms to generate a 24-bit address for each bus. The DSP has three functions that support access to the full memory map.

BA6289 应用
The INT5130 implements Intellons patented PowerPacket OFDM technology and is fully compliant with the HomePlug Powerline Alliance Industry Specification v1.0. Specifically tailored to reliably deliver up to 14 Mbps over the difficult powerline communication environment, the INT5130 combats deep attenuation notches, noises sources, and multi-path fading by allocating usable frequencies according to the signal to noise ratio (SNR). Synchronization is achieved in low SNR channels without the use of pilot carriers. The MAC implements a CSMA/CA scheme with prioritization and automatic repeat request (ARQ) for reliable delivery of Ethernet packets via packet encapsulation. Built-in quality-of-service (QoS) features provide the necessary bandwidth for multimedia payloads including voice, data, audio, and video. Prioritized random access along with segment bursting minimizes the demands on the receiver resources and maximizes the throughput of the network while still providing excellent latency response and jitter performance. The INT5130s contention-free access capability extends this concept of segment bursting to allow the transmission of multiple frames over the powerline without relinquishing the control of the medium. Utilizing contention-free access, a single station may act as a controller for the entire network.
