In supervisor mode, all processor resources are accessible from the running process. From Wikipedia, the free encyclopedia. Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions.
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. The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices.
This page was last edited on 14 Septemberat However, when in user mode, system resources and regions of memory can be protected with the help of recerence MPU. For other uses, see Referene disambiguation. Code and data can be mixed in L2. Views Read Edit View history. 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 blacofin 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. This article is about the DSP microprocessor.
They can support hundreds of megabytes of memory in the external memory space.
Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external memory. Please improve this by adding secondary or tertiary sources. Blackfin supports three run-time modes: This article relies too much on rrference to primary sources. Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes.
These features enable operating systems. This allows the processor to execute up to three instructions per clock cycle, depending on the prgramming of optimization performed by the compiler or programmer.
Blackfin – Wikipedia
ADI provides its own software development toolchains. The ISA is designed for a high refetence of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present. Retrieved April 9, Archived from the progeamming on April 17, 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.

For some applications, the DSP features are programing. All of the peripheral control registers are memory-mapped in the normal address space. The MPU provides protection and caching strategies across the entire memory 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 memory runs slower than the core clock speed. Retrieved from ” https: Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. Archived from the original on The Blackfin architecture encompasses various CPU models, each targeting particular applications. The Blackfin uses a byte-addressableflat memory map.
