Types of buses

Types of buses

1. Types of buses for your use

   • Address Bus
     • Unidirectional
     • 2n diirections
     • E/S
   • Data Bus
     • Bidirectional
     • Data can flow to or from the CPU
     • The "m" terminal can be inputs or outputs
     • It's used to transmit other information along with the data
     • The data bus is shared or multiplexed in time
     • 8 bits standar
   • Control Bus
     • Synchronizes activities and transactions with system peripherals
     • R/W signals
     • Perpherals can also issue control signals to the CPU
       • INT,RESET,BUS RQ
     • Clock signals

2. Buses

   • A line interconnecting information carrier
   • Consist of several
     • Conductor wires
     • Several chanels
     • Carries one bit of information
   • 16 lines = 16 bits
   • Expansion Slots

3. Types of buses by physical location

   • Internal
     • Moves data between the internal components of the microprocessor
     • Various power lines
     • They are like blood vessels
   • External
     • This is used to communicate the micro and elsewhere, as peripheral and memory

4. Buses ISA

   • INDUSTRY STANDARD ARQUITECTURE
   • First PC
     • Slots 8 bits

5. Buses MCA

   • ARQUITECTURA DE BUS MICROCANAL
   • IBM
   • Slots 32 bits
   • Exclusive IBM

7. Buses EISA

   • EXTENDED INDUSTRY STANDARD ARQUITECTURE
   • It has features of the ISA as to its compatibility
   • MCA speed
     • 32 bits

8. Buses VESA

   • VIDEO ELECTRONICA STANDARD ASOCIATION
   • They are an extension of ISA
   • Microprocessor running at pace
   • Faster

9. Buses PCI

   • PERIPHERICAL COMPONENT INTERCONECT
   • Peripheral component interconnect
   • Similar to VESA
   • 10 slots

10. Bus AGP

    • Advanced Graphics Port
    • It is a new bus
    • Above PCI
    • For new cards 3d

11. CardBus

    • PCMCIA
      • 2 slots
      • PC Card

12. USB

    • Universal Serial Bus
    • Was made by 7 companies
    • 1.5 Mb/s - 600 Mb/s
    • Reduces outlets
    • Asynchronous
