Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.

The purpose of this project is to explore the issues and implementation of a multiple instruction stream, single data stream processor. We are running two instruction streams on two CPUs which share an address space. The processors share a second level cache, and maintain coherence at the L1 cache with a write-invalidate policy. The L2 cache is two-way set associative, with a block size of 8 words, and a total capacity of 512 words.

Microprocessors are getting smaller, cheaper and faster. Every day, it is easier to embed more functionality into a smaller space. Embedded processors have become pervasive, and as time goes on, more and more functions that were once implemented with analog circuitry or with electromechanical assemblies are being realized with microcontrollers, ADCs and DACs. Many of these assemblies that are being supplanted by the microprocessor are controlling dynamic processes, which is a good thing, because the microprocessor coupled with the right software is often the superior device.

The design and manufacturing of wireless radio frequency (RF) transceivers has developed rapidly in recent ten yeas due to rapid development of RF integrated circuits and the evolution of high-speed digital signal processors (DSP). Such high speed signal processors, in conjunction with the development of high resolution analog to digital converters and digital to analog converters, has made it possible for RF designers to digitize higher intermediate frequencies, thus reducing the RF section and enhancing the overall performance of the RF section.

eMMC存儲介質(zhì)目前越來越廣泛的應(yīng)用在嵌入式系統(tǒng)中，AM335x的用戶也越來越多的使用EMMC作為系統(tǒng)的主要存儲介質(zhì)。目前 AM335x的幾款官方demo板中，只有BeagleBone Black上加入了對eMMC芯片的支持，很多用戶也是參考 BeagleBone Black進行自己AM335x系統(tǒng)的eMMC設(shè)計。筆者最近分別通過 TI Uniflash和SD卡完成了BeagleBone Black上 eMMC芯片的燒寫驗證工作，軟件基于 AM335x Linux SDKO6總結(jié)出來供大家參考。1，使用TI UniFlash工具通過USB RNDIS堯?qū)?.1 TI Uniflash簡介Uniflash是TI開發(fā)的存儲器燒寫工具，可以支持 AM335x系統(tǒng)的NAND Flash NOR Flash，SPI Flash eMMC燒寫。可以參考 wiki上的guide：btto://processors.wiki.ti.com/index.php/Sitara Uniflash Quick Start Guide，在Windows宿主機上下載并安裝 Uniflash，并按照其中 3.3節(jié)所述在Windows宿主機上安裝USB RNDIS驅(qū)動。1.2 eMMC燒寫原理本文介紹的驗證方法是使用 Uniflash工具通過USB對BeagleBone Black上的eMMC進行燒寫，原理是通過Romcode，SPL和u-boot三個階段，將一個專門用于 eMMC燒寫的Linux操作系統(tǒng)在BeagleBone Black板上運行起來，并自動運行腳本進行燒寫。
