Hello, readers welcome to the new post. We will discuss Difference between DSP Processor and Microprocessor. The normal microprocessor does not have features to connect with the different software and languages. This process is used on PCs.They helped to perform the computation of multimedia play, editing of texts communication with different systems
The basic difference is that the DSP process is used to give high-value performance repetition numerical operations. DSP processors are used to solve complicated mathematical operations than a normal microprocessor. We will discuss different parameters to find the differences. So let’s get started.
Difference between DSP Processor and Microprocessor
What is DSP Processor
- The DSP stands for the digital signal processor is a special type of microprocessor having a structure that is designed to perform digital signal processing.
- These processors are created on the MOS ICs board.
- Their common applications are audio signal processing, digital image processing, radar sonar, and HDTVs
- The main purpose of DSP is to calculate filter and compress analog signals.
- Mostly general purpose microprocessors operate on the digital single processing and do not have features to retain this service regularly.
- Some certain DSP comes with high-quality efficiency so mostly used in mobile phones since it part of the battery
- DSP uses a certain level of memory units which has features to ge the numerous data levels
Main Parts of DSP
- The main parts of DSP are described here
- Program Memory: This memory unit is used to store the programs to process data
- Data Memory: It stores the information that has to process
- Compute engine: It performs the mathematical operation, accesses the program from the memory unit, and also accesses data from the data memory unit
- I/O: Used to perform the different functions to attach the outer components
What is Microprocessor
- The micro process is used in the computer where data processing logic and control is added at an IC.
- It consists of arithmetic logic and control circuits to do the functions of a computer.
- The IC has features of describing and implementing programs and doing arithmetic operations
- The IC can explain and operate the functions and arithmetic operations
- Microprocessors consist of combinational logic and sequential digital logic and work on numeric and symbolic binary numbers
- The combination of complete CPUs at one or more IC makes VLSI reduce the expenses of processing power.
- IC processors are generated in larger quantities through the use of MOS fabrication techniques
- Before the use of microprocessors, small-size computers were created through the use of racks of PCB boards having numerous medium and small scale IC called TTL.
- Microprocessors linked this in single or larger ICS
DSP Processor and Microprocessor
- In DSP processor instructions are applied through the use of one clock cycle and the microprocessor uses many cycles
- DSP applies commands in a parallel fashion and the microprocessor applies in series
- DSP has separate memories for data and programs while microprocessors not have
- Program and data memoirs are built on the board for DSP and the microprocessor has no cache memory
- Program flow is measured by the program sequencer and instruction register in DSP while the microprocessor program counter observes the flow of execution
- Numerous operands can be fetched at the same time in DSP and in microprocessor, this process occurs in series
- DSP has address and data busts no multiplex and in microprocessors are multiplexed
- DSP has ALU MAC and shifter while microprocessor has only ALU
- DSP has a distinct address and data bus for data and program memory unit while microprocessor has direct indirect register etc
Microprocessor Basics
- Microprocessors get large numbers of instructions in the form of machine language and apply and instruct the processor to use that instruction
- There are three main functions performed by the Microprocessors
- It programs addition, multiplication division, and subtraction through use of ALU. Currently created microprocessors perform the functions at floating points
- Data can be transferred from points other in this modules
- It comes with PC registers which save the address of coming commands configured on the value of the personal computer.
DSP processor vs Microprocessor
DSP processor
- Instructions are applied in a single clock cycle.
- It offers parallel instruction execution.
- It comes with separate data and program memory
- It has program and data memories on-chip extendable off-chip.
- Program sequencers and instructions registers handle program flow
- Pipelining is applied through instructions registers and instruction cache.
- Different operands fetched at the same time.
- It does not have a multiplexed address and data bus and is separated on chip also off-chip.
- It comes with 3 distinct computational units for example ALU, MAC, and shifter.
- It has a distinct address and data bus for programming and data memory
- It has address mode types are Direct and indirect addressing modes.
Microprocessor
- Different clock cycles are used for the application of single instruction.
- It applies instructions in sequence form
- It does not have distinct memories.
- Generally, on-chip cache memory exists and main memory is off-chip
- Execution flow is controlled with the program counter
- In sequence form, operands are fetched.
- It comes with a multiplexed address and data bus.
- It comes with a single main unit ALU.
- It comes with an address and data are 2 buses on chip.
