Blackfin – Wikipedia

Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions. This page was last edited on 14 Septemberat Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external memory. For some applications, the DSP features are central. Referencw from the original on Retrieved April 9, The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features referencd.

From Wikipedia, the free encyclopedia. This allows the processor to execute up to three instructions per clock cycle, depending on referencs level of optimization performed by the compiler or programmer. Archived copy as title Articles lacking reliable references from December All articles lacking reliable references Articles needing additional references from December All articles needing additional references.

Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes. Please improve this by adding secondary or tertiary sources. Programking of the peripheral control registers are memory-mapped in the normal address space.

Blackfin Processors: Manuals

The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller. By using this site, you agree to the Terms of Use and Referwnce Policy. If a thread crashes or attempts to access a protected resource memory, peripheral, etc. Code and data can be mixed in L2. The MPU provides protection and caching strategies across the entire memory space.

Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. In supervisor mode, all processor resources are accessible from the running process. They can support hundreds of megabytes of memory in the external memory space.

This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures. Retrieved from ” https: This article is about the DSP microprocessor. ADI provides its own software development toolchains.

The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions.

However, when in user mode, system resources and regions of memory can be protected with the help of the MPU. These features enable operating systems. 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 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. 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 section does not cite any sources. Blackfin supports three run-time modes: Reduced instruction set computer RISC architectures.


This memory runs slower than the core clock speed. 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 architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, The Blackfin uses a byte-addressableflat memory map. 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.

Views Read Edit View history. The Blackfin architecture encompasses various Reterence models, each targeting particular applications.

Archived from the original on April 17, 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.
