TigerSHARC处理器：多处理器应用的首选器件ADI

简介：

问：什么是EDRAM?它和DRAM有何不同?存储器单元是什么样结构?
答： EDRAM is embedded DRAM. Structure is one transistor per cell.

问：2.在DSP比较时,BBENCHMARK的具体含义,为什么说 The smaller the benchmark number, the quick the algotithm execution?在BENCHMARK 中提到了 ON-CHIP SRAM SIZE,DAM CHANNELS,DATA REGISTER,CIRCULAR BUFFERS,难道这些指标也要小吗?
答： We agree, "ON-CHIP SRAM SIZE,DMA CHANNELS,DATA REGISTER,CIRCULAR BUFFERS," are not benchmarks but processor attributes or features. A smaller benchmark is better only if the benchmark represents TIME to execute.

问：是否适合用于汽车自主导航系统的主机？
或者AD公司有其他芯片可以用于这个方面？是否有应用案例？

答： Yes, TigerSHARC can be used in this application. Other ADI DSPs can also be used as well such as Blackfin.

问：请举一个TigerSHARC在机器视觉方面的例子？
答： TigerSHARC can be used for doing video encoding and decoding especially in multimedia streaming etc. Similarly, TigerSHARC is also used for radar and sonar imaging.

Apart from this, TigerSHARC is a great DSP with lots of compute power and hence i

问：在并行处理时具备什么优势？
答： 很高的DSP间通信能力。包括LinkPort和Cluster bus。每个LinkPort提供1Gbyte的吞吐能力，Cluster bus也是1G的总线。所以DSP间通信的速度非常块。

问：Tiger的总线驱动能力如何？

答： TS总线支持8片DSP互连，另外可以通过外部配置管脚的上下拉状态调整总线的驱动电流和阻抗

问：我在做雷达信号处理系统（信号增强、处理、成像），该需要几个处理器，在设计时，按你们的经验，需多长时间，与TI的C6X系列相比较如何？
答： TigerSHARC can handle twice the number of 16-bit MAC operations as C64x and can TigerSHARC can support IEEE floating point directly while TI C64x cannot.

TigerSHARC supports glueless multiprocessor connectivity whereas TI cannot.

问：因为开始时选择了TI的产品，后来感觉他们的技术支持不能令人满意，你们在中国的相关产品的技术支持力量如何
答： China is has a team of dedicated DSP FAEs. In addition, there is a China Application Support
which supports customers thru email and phone.

问：TI的DSP产品中，有没有与TigerSHARC处理器相类似的产品，可用于通用信号处理系统中？
答： 对不起，请向TI咨询类似问题。

问：和SHARC相比，TigerSHARC有哪些明显的优点？
答： TigerSHARC has more on-chip memory, higher degree of parallelism, higher bandwidth, higher clock rate and greater flexibility in host and multiprocessing systems.
