Type Members

1. trait AddressMapping extends AnyRef

   

2. trait AddressTransformer extends AnyRef

   

   Model a transformation on a address, typicaly, an address decoder may apply an offset to each of its outputs

3. trait BusSlaveFactory extends Area

   

   Bus slave factory is a tool that provide an abstract and smooth way to define register bank

4. class BusSlaveFactoryAddressWrapper extends BusSlaveFactory

   

5. case class BusSlaveFactoryConfig(wordEndianness: Endianness = LITTLE) extends Product with Serializable

   

   Configuration of the bus Slave Factory

   Configuration of the bus Slave Factory

   wordEndianness

   Endianness for the multiWrite or multiRead operations

6. trait BusSlaveFactoryDelayed extends BusSlaveFactory

   

   BusSlaveFactoryDelayed captures each primitives (BusSlaveFactoryElement) into a data-model

   BusSlaveFactoryDelayed captures each primitives (BusSlaveFactoryElement) into a data-model

   Example:

   1. class Apb3SlaveFactory(bus : Apb3) extends BusSlaveFactoryDelayed{
          override def build(): Unit = { ... }
          override def busDataWidth: Int = bus.config.dataWidth
       }

7. trait BusSlaveFactoryElement extends AnyRef

   

   Base element

8. case class BusSlaveFactoryNonStopWrite(that: Data, bitOffset: Int, documentation: String) extends BusSlaveFactoryElement with Product with Serializable

   

   Ask to constantly drive that with the data bus bitOffset specify where that get bits from the request

9. case class BusSlaveFactoryOnReadAtAddress(address: AddressMapping, haltSensitive: Boolean, documentation: String, doThat: () ⇒ Unit) extends BusSlaveFactoryElement with Product with Serializable

   

   Ask to execute doThat when a read access is done on address

10. case class BusSlaveFactoryOnWriteAtAddress(address: AddressMapping, haltSensitive: Boolean, documentation: String, doThat: () ⇒ Unit) extends BusSlaveFactoryElement with Product with Serializable

    

    Ask to execute doThat when a write access is done on address

11. case class BusSlaveFactoryRead(that: Data, address: AddressMapping, bitOffset: Int, documentation: String) extends BusSlaveFactoryElement with Product with Serializable

    

    Ask to make that readable when an access is done on address bitOffset specify where that is placed on the answer

12. case class BusSlaveFactoryWrite(that: Data, address: AddressMapping, bitOffset: Int, documentation: String) extends BusSlaveFactoryElement with Product with Serializable

    

    Ask to make that writable when a access is done on address.

    Ask to make that writable when a access is done on address. bitOffset specify where that get bits from the request

13. case class InterleavedMapping(mapping: AddressMapping, blockSize: Int, ratio: Int, sel: Int) extends AddressMapping with Product with Serializable

    

14. case class InterleaverTransformer(blockSize: Int, ratio: Int, sel: Int) extends AddressTransformer with Product with Serializable

    

15. case class InvertMapping(inv: AddressMapping) extends AddressMapping with Product with Serializable

    

16. case class MaskMapping(base: BigInt, mask: BigInt) extends AddressMapping with Product with Serializable

    

    Creates an address mapping using a bit mask.

    Creates an address mapping using a bit mask.

    MaskMapping(0x0000, 0x8000) => matches 0x0000-0x8000 MaskMapping(0x40, 0xF0) => matches 0x40 - 0x4F

    base

    Address offset to use. Must be inside the mask

    mask

    Bit mask applied to the address before the check

17. case class OffsetTransformer(offset: BigInt) extends AddressTransformer with Product with Serializable

    
    offset

    For instance, if a slave is mapped at address 0x100 of a master => offset = 0x100

18. case class OrMapping(conds: Seq[AddressMapping]) extends AddressMapping with Product with Serializable

    

19. case class SingleMapping(address: BigInt) extends AddressMapping with Product with Serializable

    

20. case class SizeMapping(base: BigInt, size: BigInt) extends AddressMapping with Product with Serializable

    

21. case class SizeMappingInterleaved(base: BigInt, size: BigInt, blockSize: Int, pattern: Seq[Boolean]) extends AddressMapping with Product with Serializable

    

22. case class UnmaskMapping(base: BigInt, mask: BigInt) extends AddressMapping with Product with Serializable
