Blackfin Processors: Manuals
This article is about the DSP microprocessor. The Blackfin architecture encompasses various Blakfin models, each targeting particular applications. For some applications, the DSP features are central. Please improve this by adding secondary or tertiary sources. December Learn how and when to remove this template message.
Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions. Views Read Edit View history.
The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller.
From Wikipedia, the free encyclopedia. Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes. Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. What is regarded as the Blackfin “core” is contextually dependent.
Retrieved April 9, 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 blacjfin a variety of on-chip peripherals.

Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external memory. If a thread crashes or attempts to access a protected resource memory, peripheral, etc.

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 supports three run-time modes: However, when in user mode, system resources lbackfin regions of memory can be protected with the help of the MPU. This article relies too much on references to primary sources. The ISA is designed for a reterence level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present.
They can support hundreds of megabytes of memory in the external memory space.

Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors. Code and data can blackffin mixed in L2. Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions. All of the peripheral control registers are memory-mapped in the normal address space.
Reduced instruction set computer RISC architectures. The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, Retrieved from ” https: 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.

This memory runs programminh than the core clock speed. The official guidance from ADI on how to use the Blackfin in non-OS environments is to reserve the lowest-priority interrupt for general-purpose code so that all software is run in supervisor space.

For other uses, see Blackfin disambiguation. This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures. 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 MPU provides protection and caching strategies across the entire memory space. Instruction memory and data memory are independent and connect to the core via dedicated memory buses, designed for higher sustained data rates between the core and L1 memory. These features enable operating systems. In supervisor mode, all processor resources are accessible from the running process.
