The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. The processors have built-in, fixed-point. his chapter examines the architecture of the Blackfin processor, which is based on the MSA jointly developed by Analog Devices and Intel. We use assembly. Analog Devices Blackfin /bit Embedded Processors are available at Mouser and offer software flexibility and scalability for convergent applications.

Blackfin processors architecture is also fully SIMD compliant and includes instructions for accelerated video and image processing.

However, when in user mode, system resources and regions of memory can be protected with the help of the MPU.

Code and data can be mixed in L2. Blsckfin Processors are a new breed of bit embedded microprocessor designed specifically to meet the computational demands and power constraints of today’s embedded audio, video and communications applications.
Thus, the MMU offers an isolated and secure environment for robust systems and applications. Processor Options – One option for each supported Blackfin model.
Please Select a Language. When combined, these two features enable Blackfin Processors to deliver code density benchmarks comparable to industry-leading RISC processors. This capability greatly simplifies both the hardware and software design implementation tasks. 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.
Source code to the run-time libraries is available so that users can customize routines according to the special needs of their applications. These instructions can be fully optimized by the compiler. What is regarded as the Blackfin “core” is contextually dependent.
Reduced instruction set computer RISC architectures. In supervisor mode, all processor resources are accessible from the running process. Archived from the original on The L1 memory structure has been implemented to provide the performance needed for signal processing while offering the programming ease found in general purpose microcontrollers.
All Blackfin Processors offer fundamental benefits to the system designer which include: The intrinsic functions are recognized by the compiler, which generates very efficient Blackfin Processor code inline: This page was last edited on 14 Septemberat The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present.
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. Blackfin Processors are based on a gated clock core design that selectively powers down functional units on an instruction-by-instruction basis.
The Blackfin Processor architecture supports multi-length instruction encoding. The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller. This combination of processing attributes enables Blackfin Processors to perform equally well in both signal processing and control processing applications-in many cases deleting the requirement for separate heterogeneous processors.
This section does not cite any sources. Lastly, and probably most importantly, these embedded microprocessors support a self contained dynamic power management scheme whereby the operating frequency AND voltage can be independently manipulated to meet the performance requirements of the algorithm currently being executed. The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, 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.
The L1 memory is connected directly to the processor core, runs at full system clock speed, and offers maximum system performance for time critical algorithm segments. The resulting instructions can be fully optimized by the compiler.
The Blackfin Processor family also offers industry leading power consumption performance down to 0. All of the peripheral blaackfin registers are memory-mapped in the normal address space. A single Blackfin Processor can be processoe in many applications previously requiring both a high performance signal processor blaclfin a separate efficient control processor. December Learn how and when to remove this template message.
This is accomplished by allowing the L1 memory to be configured as SRAM, cache, or a combination of both. This benefit greatly reduces development time and costs, ultimately enabling end products to get to market sooner. Easy to Use A single Blackfin Processor can be utilized in bblackfin applications previously requiring both a high performance signal porcessor and a separate efficient control processor. This article is about the DSP microprocessor. Simbf also simulates both the caches and the instruction pipeline.
This memory runs slower than the core clock speed. Circular Buffer Support – The Blackfin Processor compiler can generate circular procesxor increments from intrinsic functions or directly from C code.
With the optimal code density and the possibility of little to no code optimization, quicker time to market can be achieved without running into performance headroom barriers seen on other traditional processor. Debug each core or processor in a separate color-coded window View and select cores or processors from a list Select one or more cores or processors and assign them to a group Run, step, or halt a single core or processor or the entire group Instruction Set Simulator – The simbf instruction set simulator interpretively executes Blackfin Processor programs on the host PC, Linux, or UNIX workstation without the requirement of target hardware by simulating the execution of the target processor at the instruction level.
This article relies too much on references to primary sources. All Blackfin Processors employ multiple power saving techniques.

This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures.
