BaseMemory (const char *name, int slotID, unsigned int regID, int r, int w, int len=1, int addrShift=0, int blockLen=1, bool useCache=false)
void readBlockAutoIncr (int elem, unsigned long *data, unsigned long start, unsigned long blockLen)

Detailed Description

The class contains the register address modell of the SLT board.

The individual register address is calculated from the slot ID and the register ID.

The register implementation contains a cache function to avoid unneccessary access to the hardware. To decode the status bits the cache content can be used without storing any additional intermediate data.

Constructor & Destructor Documentation

hw4::BaseMemory::BaseMemory	(	const char *	name,
		int	slotID,
		unsigned int	regID,
		int	r,
		int	w,
		int	len = `1`,
		int	addrShift = `0`,
		int	blockLen = `1`,
		bool	useCache = `false`
	)

A register (slt object) is defined by it's name and the combination of slot ID and register ID.

Every register also posses the properties readable and writeable. The register object can also be used to access register vectors and memories. For a register vector the number of elements and the address shift needs to be specified. A memory also needs both parameters. Memories span a contiouous space so that block access can be used to get the data for all elements.

void hw4::BaseMemory::readBlockAutoIncr	(	int	elem,
		unsigned long *	data,
		unsigned long	start,
		unsigned long	blockLen
	)

Read all elements of the memory using the DataBlock register in the Pbus-layer.
