USB host and device controller driversUSB is not a peer to peer protocol, like TCP/IP. There is one master, called the host, and one or more slaves, called devices or peripherals. If you want to connect USB devices, such as USB disk drives, USB printers, etc. To your embedded device, then you need a USB host stack, such as.

On the other hand, if you want to connect your embedded device to a PC and look like a USB device, then you need a USB device stack, such as. OTG is for embedded devices that need to be able to connect to other OTG devices and switch roles of themselves and their peer. We support this with.General InfoOur USB products can be used with other RTOSs or standalone. When used with our multitasking kernel, they operate out-of-the-box on supported and include.

Topics include:. “What are Blackfin Processors?” on page 1-1. “Blackfin Processor Features” on page 1-22. “Benchmarks Against Other Processors” on page 1-26.If the application demands, the Blackfin processor can act as 100% MCU (with code den- sity on par with industry standards), 100% signal processor (with clock rates at the leading edge of signal processor technology), or a combination of the two.DCB2 MXVR DEB2 DCB3 Figure 1-1.

Single Core ADSP-BF549 Blackfin 16/32-Bit Processor Blackfin processors support both protected and unprotected operating modes that prevent users from accessing or affecting shared parts of the system. In addition, the processors provide memory management.MCU programmers, for example, may prefer implementing a turnkey system and letting it perform all tasks without user intervention. With this in mind, Blackfin processors were designed to support both DMA and cache memory controllers to move data through a system. Mul.This enables developers to leverage enormous amounts of existing application code developed from previous efforts. Because Blackfin processors are optimized for both control and signal pro- cessing operations, compilers can generate code that is both tight (from a code density standpoint) and efficient (for computationally-intensive sig- nal processing applications).Finally, for scalable Blackfin architectures, designers can base their work around the most capable member of the Blackfin processor family, and can use a cost-optimized processor. Dual-Core Processors Add Flexibility Blackfin processors are also available as dual-core devices.Blackfin processors are designed to offer feature-packed, future-ready architectures for media-rich applications. Blackfin Processors (Currently Available) The ADSP-BF535 was the first released Blackfin processor, followed in March 2003 by three pin-compatible devices, the ADSP-BF531, ADSP-BF532, and ADSP-BF533 Blackfin processors.

These three devices offer a range of memory and speed options, providing maximum scalabil- ity and design flexibility.What are Blackfin Processors? In January of 2005, Analog Devices introduced three Blackfin processors with embedded connectivity: the ADSP-BF536, ADSP-BF537, and ADSP-BF534. These three devices are also pin-compatible with each other and include controller area network (CAN), twin-wire interface (TWI) peripherals, and on some models, a 10/100 ethernet MAC.All processors noted as “RoHS Compliant” are also lead free. Also, unless they differ from processor to processor, the key periph- erals are listed in the row designating the Blackfin family in bold typeface (such as ADSP-BF522).

Because Blackfin processors possess all the power of a signal processor and are full featured, they can replace other classes of signal processors and 32-bit RISC MCUs or an ASIC in designs.The width of a processor is typically mea- sured by its data paths and register widths.

Blackfin processors support 8-, 16-, and 32-bit arithmetic operations in hardware, but are optimized for (and have the most support for) 16-bit operations.Figure 1-3 shows a chart that demonstrates power consumption versus speed for a 750 MHz Blackfin processor and various devices. What follows is the Berkeley Design Technology, Inc. (BDTI) text description of the figure: BDTImark2000™.All rights reserved. Power Consumption Versus Speed for Various Devices dropped to values as low as 0.9 V. This is possible because of the Blackfin processor’s wide voltage operating range. Dual-core Blackfin processors contain large amounts of on-chip memory along with data paths and DMA controllers that have been sized specifically to handle a shared pro- cessing load. Only a small amount of global data is manipulated (as opposed to Whetstone).
