Blackfin Processors: Manuals

Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors. 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.

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.

Code and data can be mixed in L2. The ISA is designed for a high level of expressivenessprogdamming the assembly programmer or compiler to optimize an algorithm for the hardware features present. Archived from the original on April 17, In other projects Wikimedia Commons. For some applications, the DSP features are central.

Blackfin – Wikipedia

Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. This page was last edited on 14 Septemberat All of the peripheral control registers are memory-mapped in the normal address space. In supervisor mode, all processor resources are accessible from the running process.


From Wikipedia, the free encyclopedia. However, when in user mode, system resources and regions of memory can be prograkming with the help of the MPU.

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.

Retrieved April 9, This article is about the DSP microprocessor. The Blackfin architecture encompasses various CPU models, each targeting particular applications. This memory runs slower than the core clock speed. Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions.

ADI provides its own software development toolchains. The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates Programmnigaccompanied on-chip by a small microcontroller. The MPU provides protection and caching strategies across the entire memory space.

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. Views Read Edit View history.

Please improve this by adding secondary progranming tertiary sources. Retrieved from ” https: The Blackfin uses a byte-addressableflat memory map. December Learn how and when to remove this template message.


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

If a thread crashes or attempts to access a protected resource memory, peripheral, etc. Please help improve this section by adding citations to reliable sources. This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures.

Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external memory. Unsourced material may be challenged and removed. By using this site, you agree to the Terms of Use and Privacy Policy.
