The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. The processors have built-in, fixed-point. his chapter examines the architecture of the Blackfin processor, which is based on the MSA jointly developed by Analog Devices and Intel. We use assembly. Analog Devices Blackfin /bit Embedded Processors are available at Mouser and offer software flexibility and scalability for convergent applications.

Internal L1 memory, internal L2 memory, external memory and all memory-mapped control registers reside in this bit address space, so that from a programming point of view, the Blackfin has a Von Neumann architecture. December Learn how and when to remove this template message. High-performance signal processing and efficient control processing capability enabling a variety of new markets and applications.
This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures.

When combined, these two features enable Blackfin Processors to deliver code density benchmarks comparable to industry-leading RISC processors. Blackfin processors architecture is also fully SIMD compliant and includes instructions for accelerated video and image processing. Reduced instruction set computer RISC architectures.
Video Instructions In addition to native support for 8-bit data, the word size common to many pixel processing algorithms, the Blackfin Processor architecture includes instructions specifically defined to enhance performance in video processing applications. Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes.
Blackfin Processors are a new breed of bit embedded microprocessor designed specifically to meet the computational demands and power constraints of today’s blaxkfin audio, video and communications applications.

The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, Superior Code Density The Blackfin Processor architecture supports multi-length instruction encoding. Blackfin supports three run-time modes: This combination of processing attributes enables Blackfin Processors to perform equally well in both signal processing and control processing applications-in many cases deleting the requirement for separate heterogeneous processors.
What is regarded as the Blackfin “core” is contextually dependent. These features enable operating systems. Blacofin transitions may occur continually under the control of an RTOS or user firmware. For other uses, see Blackfin disambiguation. Other applications use the RISC features, which include memory protection, different operating modes user, kernelsingle-cycle opcodesdata and instruction caches, and instructions for bit test, byte, word, or integer accesses and a variety of on-chip peripherals.

Circular Buffer Support – The Blackfin Processor compiler can generate circular pointer increments from intrinsic functions or directly from C code. This article is about the DSP microprocessor. The MPU provides protection and caching strategies across the entire memory space.
All Blackfin Processors have multiple, independent DMA controllers that support automated data transfers with minimal overhead from the processor core. You can change your cookie settings at any time. Please be aware that parts of this site, such as myAnalog, will not function correctly if you disable cookies. Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions. From Wikipedia, the free encyclopedia.
Host-target connectivity is provided through a variety of means, depending on the target environment. Source code to the run-time libraries is available so that users can customize routines according to the special needs of their applications. In supervisor mode, all processor resources are accessible from the running process. This allows the processor to execute up to three instructions per clock cycle, depending on the level of optimization performed by the compiler or programmer.
Blackfin Processors are based on a gated clock core design that selectively powers down functional units on an instruction-by-instruction basis. The L1 memory is connected directly to the processor core, runs at full system clock speed, and offers maximum system performance for time critical algorithm segments.

The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices.
With the optimal code density and the possibility of little to no code optimization, quicker time to market can be achieved without running into performance headroom barriers seen on other traditional processor.

They can support hundreds of megabytes of memory in the external memory space. All of these features provide the system designer with a great deal of design flexibility while minimizing end system costs.
