This application note describes how to manage the booting of multiple executables from external memory at run-time, thus providing the flexibility to dynamically switch among them. This project was implemented on the ADSP- BF561 EZ-KIT Lite® evaluation system (ADDS-BF561-EZLITE, Rev 1.1) and applies to the ADSP-BF561 Blackfin® processors with silicon revision 0.2 and beyond.
This application note provides detailed information on how to implement the interface between an ADSP-2126x SHARC® processor and MultiMediaCard™ (MMC). The application note also describes the MMC command format and demonstrates with example code how an MMC card can be interfaced seamlessly with the SHARC processor’s SPI port. The example code provided with this application note implements the most commonly used MMC commands and features.
This document explains the fundamentals of sample rate conversion (SRC) and demonstrates how to program the sample rate converters of ADSP-2136x SHARC® processors.
This document is a technical note on using ADSP-21065L and ADSP-21161 processors. It discusses the implementation of in-place FFTs and provides ASM code examples.
This application note discusses how to emulate the PCM interface using four programmable flag pins (GPIOs) of the ADSP-BF561 Blackfin® processor. This application note applies to designs in which all of the serial interfaces present on the devices are in use and hence the need for emulation of the PCM interface arises.
This EE-Note describes jitter requirements of PLL-based processors, including data-clock jitter in synchronous protocols and signal jitter in CDR (clock data recovery) applications.
This application note describes how to interface parallel ADCs to ADSP-21365 SHARC® processors. The parallel ADC considered in this application note is the AD7865. The two schemes described in this application note to interface an AD7865 with an ADSP-21365 are the parallel port interface and the parallel data acquisition port (PDAP) interface. This application note also provides examples of how to use the PDAP interface to connect AD7865 to ADSP-21365.
This document explains how to interface parallel ADCs to ADSP-21161 SHARC® processors. The parallel ADC considered in this application note is AD7865. This application note also provides example code to demonstrate how the SHARC processor’s external port can be programmed to receive data from the AD7865 in core and DMA modes.
This report summarizes the reliability data for Motorola communication microprocessors fabricated on the 0.42m single polysilicon process in our wafer fabrication facility, Mos 11, in Austin, Texas.
