Detailed Description

Represents a configuration bitstream. Provides storage for BitSettings, and an order among ConfigCells

BitArray

using BitStream::BitArray = std::vector<std::vector<BitSetting> >

Member Function Documentation

append()

void BitStream::append	(	const ConfigCell *	ccell,
		const BitArray &	bits,
		int	con_used = 0
	)

Add the given bits to the configuration database, and place ccell at the end of the ConfigCell order.

Definition at line 19 of file BitStream.cpp.

ccellOrder()

auto& BitStream::ccellOrder ( ) const

inline

The ordering among the ConfigCells.

Definition at line 60 of file CGRA.h.

printTestbench()

void BitStream::printTestbench	(	std::ostream &	os,
		const int &	II,
		bool	is_elastic = false
	)		const

Prints out a Verilog file intended to help with creating a testbench for the CGRA.

Bitstream is given all the bits for an element at once. Bits are given in order from last cycle to first cycle. From last bit to first bit.

Definition at line 44 of file BitStream.cpp.

settingFor()

const BitArray& BitStream::settingFor ( const ConfigCell *  cc ) const

inline

Get the configuration for a particular ConfigCell throws if it does not exist.

Definition at line 55 of file CGRA.h.

operator<<

std::ostream& operator<< ( std::ostream &  os, const BitStream &  bs  )

friend

Print the bitstream in a human-friendly way.

Prints out the bit settings for each element. For each element, the bit setting is printed from cycle 0 to II, from first bit to last bit
