          The AMIC110 device is a multiprotocol programmable industrial communications processor providingready-to-use solutions for most industrial Ethernet and fieldbus communications slaves, as well as somemasters. The device is based on the ARM Cortex-A8 processor, peripherals, and industrial interfaceoptions. The device supports high-level operating systems (HLOS). Linux? and TI-RTOS are available freeof charge from TI. Other RTOS are also offered by TI ecosystem partners. The AMIC110 microprocessoris an ideal companion communications chip to the C2000 family of microcontrollers for connected drives.

          The AMIC110 microprocessor contains the subsystems shown in Figure 1 and a brief description ofeach follows:The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor. The PRU-ICSS isseparate from the ARM core, allowing independent operation and clocking for greater efficiency andflexibility. The PRU-ICSS enables additional peripheral interfaces and real-time protocols such asEtherCAT, PROFINET IRT, EtherNet/IP, PROFIBUS, Ethernet Powerlink, Sercos III, and others.

          Additionally, the programmable nature of the PRU-ICSS, along with its access to pins, events and allsystem-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, specializeddata handling operations, custom peripheral interfaces, and in offloading tasks from the other processorcores of SoC.

          【相關信息】詳解TI ARM架構Stellaris MCU和Sitara MPU

          德州儀器(TI)公司推出30多款全新ARM器件。這是繼TI收購ARM Cortex-M3廠商Luminary公司以后的在ARM架構處理器開發方面的一個大動作。

          ARM處理器在嵌入式領域市場增長迅速,尤其在工業和醫療電子領域,年復合增長率分別達到27.8%和65.4%。實際上,TI是早在1993年就獲得了首款ARM內核許可證,并與1995年推出首款單芯片DSP/ARM數字基帶產品。其后,TI先后推出用于數字視頻的ARM9的達芬奇處理器、車載應用的ARM Cortex-R4單片機TMS570系列和基于Cortex A8的高性能OMAP系列處理器。加上Luminary Cortex-M3的引入,TI現在提供從最低1美元起直到速度超過1GHz的多種ARM產品,基于ARM技術的產品出貨量已經超過50億顆。

          現在,TI的嵌入式處理器產品更加豐富。數字信號處理器(DSP)是TI的絕對優勢產品。李檢說,TI致力于使DSP編程越來越容易,TI網站上提供許多開源代碼供用戶免費下載。然而,相對來說,更多的人對ARM比較熟悉。ARM公司今年來的推廣普及工作效果顯著,很多人更愿意采用ARM架構的處理器。此次TI公司推出的Cortex-M3 MCU和Cortex-A8 MPU就是為了順應這種趨勢。在MCU方面,TI的超低功耗MSP430系列已經非常成功,性能超過競爭的8位單片機,成本上也與8位機相當。TI原有的C2000系列的特點是實時處理能力超群,其模擬接口速度快、精密度高,在特定領域具有顯著優勢。這樣,基于Cortex-M3的Stellaris系列MCU與TI原有的MSP430、C2000共同組成了TI豐富的MCU產品陣營。Cortex-M3 MCU的優勢是通信接口完善(具備以太網PHY、USB等),以及內存速度快,在一個時鐘周期內完成讀寫。

          新的Sitara系列MPU是從TI原有的OMAP處理器基礎上演變出來的產品,其中包括ARM9內核和Cortex-A8內核的產品,具有高性能、低功耗和低BOM等綜合優勢。Cortex-A8器件性能最高,甚至可以作為上網本處理器使用。在相同主頻下,Cortex-A8的速度是ARM9的兩倍。該系列支持實時操作系統,如Linux和Windows Embedded CE。另外,該系列MPU具有低功耗的特點,以不足1W的功耗實現1000 Dhrystone MIPS的性能。李檢說,此次推出的兩款AM35產品的功耗不到500mW。


          軟件方面,TI為Stellaris MCU和Sitara MPU提供免NRE、免專利費的支持。開發平臺方面,TI提供官方開發板。用于Stellaris的評估套件介于49到109美元之間,用于Sitaris的評估板起價149美元。李檢介紹說,國內有第三方提供的簡化Stellaris套件低至25美元。
