Blackfin Processors: Manuals

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.

The Blackfin architecture encompasses various CPU models, each targeting particular applications. The official guidance from ADI on how to rference 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. Code and data can be mixed in L2. Retrieved from ” https: In supervisor mode, all processor resources are accessible from the running process.

Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes.

Please help improve this section by adding citations to reliable sources. This page was last edited on 14 Septemberat All of the peripheral control registers are memory-mapped in the normal address space. In other projects Wikimedia Commons. They can support hundreds of referende of memory in the external memory space.


Retrieved April 9, The MPU provides protection and caching strategies across the entire memory space. The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present. The Blackfin uses a byte-addressableflat memory map. What pgogramming regarded as the Blackfin “core” is contextually dependent.

The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. ADI provides its own software development toolchains. These features enable operating systems. This article relies too much on references to primary sources.

Blackfin blakfin three run-time modes: This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures. 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.

Archived from the original on Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions. Reduced instruction set computer RISC architectures. If a thread crashes or attempts to access a protected resource memory, peripheral, etc.

The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, 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.


Blackfin processors contain an programminf of connectivity peripherals, depending on the specific processor:. This memory runs slower than the core clock speed. This article is about the DSP microprocessor. 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.

Views Read Edit View history. From Wikipedia, the free encyclopedia. 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. However, when in user mode, system refreence and regions of memory can be protected with the help programminb the MPU.

The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller. For some applications, the Referencr features are central.
