BLACKFIN PROCESSOR PDF

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.

In supervisor mode, all processor resources are accessible from the running process.

Video Instructions In addition to native support for 8-bit data, the word size common blxckfin many pixel processing algorithms, the Blackfin Processor architecture includes instructions specifically defined to enhance performance in video processing applications.

Most Blackfin processors offer on-chip core voltage regulation circuitry as well as operation to as low as 0.

The Blackfin instruction set contains media-processing extensions to help accelerate pixel-processing operations commonly used in video compression and image compression and decompression algorithms. The RTOS runs in Supervisor mode and partitions blocks of memory and other system resources for the actual application software to run in User mode. Easy to Use A single Blackfin Processor can be utilized in many applications previously requiring both a high performance signal processor and a separate efficient control processor.

The MPU provides protection and caching strategies across the entire memory space. Retrieved April 9, The intrinsic functions are recognized by the compiler, which generates very efficient Blackfin Processor code inline: The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present.

This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures. For other uses, see Blackfin disambiguation. Simbf also simulates both the caches and the instruction pipeline.

This combination of processing attributes enables Blackfin Processors to perform equally well in both signal processing and control blakfin applications-in many bpackfin deleting the requirement for separate heterogeneous processors.

Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions. Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. The resulting instructions can be fully optimized by the compiler. Circular Buffer Support – The Blackfin Processor compiler can generate circular pointer increments from intrinsic functions or directly from C code.

The Blackfin Processor family also offers industry leading power consumption performance down to 0. From Wikipedia, the free encyclopedia.

When caching and fetching instructions, the core automatically fully packs the length of the bus because it does not have alignment constraints. Debug each core or processor in a separate color-coded window View and select cores or processors from a list Select one or more cores or processors and assign them to a group Run, step, or halt a single core or processor or the entire group Instruction Set Simulator – The simbf instruction set simulator interpretively executes Blackfin Processor programs on the host PC, Linux, or UNIX workstation without the requirement of target hardware by simulating the execution of the target processor at the instruction level.

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.

The L2 memory is a larger, bulk memory storage block that offers slightly reduced performance, blackin still faster than off-chip memory. Additionally, a single set of development tools can be used, which decreases the system designer’s initial expenses and learning curve.

These features enable operating systems. They can support hundreds of megabytes of memory in the external memory space. These blackin can be fully optimized by the compiler. Blackfin Processors also support multiple power-down modes for periods where little blac,fin no CPU activity is required. Dynamic Power Management DPM enabling the system designer to specifically tailor the device power consumption profile to the end system requirements.

The processors typically have a dedicated DMA channel for each peripheral, which is designed for higher throughput for applications that can use it, such as real-time standard-definition D1 video encoding and decoding. Ultimately, Blackfin Processors will help lower overall system cost while improving the time to market for the end application.

Blackfin Processors are a new breed bllackfin bit embedded microprocessor designed specifically to meet the computational demands and power constraints of today’s embedded audio, video and communications applications.
