What is custom single purpose processor?
Processor • • • • • • • Digital circuit that performs a computation tasks Controller and datapath General-purpose: variety of computation tasks Single-purpose: one particular computation task Custom single-purpose: non-standard task A custom single-purpose processor may be – Fast, small, low power – But, high NRE.
What are the four stages of custom single purpose processor design?
Designing custom single purpose processor 1. Develop an algorithm or function that computes the desired output. 4. Complete controller design by implementing FSM with combinational logic.
Which is single purpose processor?
Single purpose processor: good performance, small, less energy consumption but more difficult design, more expensive, less flexible. PLD: low design cost, fast product development, available in large numbers but more energy consumption than ASIP. Some examples are: PLA, FPGA.
What is GPP in embedded system?
General Purpose Processor (GPP): GPP is used for processing signal from input to output by controlling the operation of system bus, address bus and data bus inside an embedded system.
What is design technology in embedded system?
Definition: A system designed with the embedding of hardware and software together for a specific function with a larger area is embedded system design. In embedded system design, a microcontroller plays a vital role. External processor, internal memory and i/o components are interfaced with the microcontroller.
What is the difference between single purpose processors and general purpose processors?
General Purpose processor is a macro processor that is not tied or integrated with a specific software or language. Single Purpose processor is related to Application Specific Integrated Circuit or ASIC that serves only one purpose.
Is CPU a special purpose processor?
A special-purpose processor, such as a DMA controller or Fourier transformer, performs a specific function. A custom processor is synthesized to quickly execute a set of functions, but is harder to design and modify.
What is meant by Harvard architecture?
The Harvard architecture is a computer architecture with separate storage and signal pathways for instructions and data. The term originated from the Harvard Mark I relay-based computer, which stored instructions on punched tape (24 bits wide) and data in electro-mechanical counters.
Which are the two lines used in the I2C?
Explanation: The I2C bus consists of two lines which are called SDA and SCL. The master and slave devices are attached to these lines.
What are the design constraints for designing for embedded system?
Embedded systems design must even-handedly deal with both: with computation and physical constraints; with software and hardware; with abstract machines and transfer functions; with nondeterminism and probabilities; with functional and performance requirements; with qualitative and quantitative analysis; with booleans …
