Flow Control Library

Purpose

The flow-control library contains all casper_flow_control HDL modules wrapped for Simulink. These blocks provide combinatorial entities to redirect standard logic-vectors.

Bus Create

Concatenates many input bus to create a unified output bus.

Ports

Signal	Type	Size	Description
din_0…	std_logic_vector	any	The input vectors
dout	std_logic_vector	any	The output vector

Parameters

Generic	Type	Value	Description
Input Bit Widths	Comma-delimited Integers	4,1,2,1	The bit-width of each input vector

Bus Expand

Breaks the input bus out into many smaller, constituent output buses.

Ports

Signal	Type	Size	Description
din	std_logic_vector	any	The input vector
dout_0…	std_logic_vector	any	The output vectors

Parameters

Generic	Type	Value	Description
Division Bit Widths	Comma-delimited Integers	1,2,3,2	The bit-width of output vectors
Radix Positions	Comma-delimited Integers	0,0,1,0	The fixed-point radix bit-position of the output vectors
Output Division Types	Comma-delimited Integers {0,1,2}	2,1,0,0	The cast-type of each output vector: (ufix=0, fix=1, bool=2)

Munge

Reorders equal-slices of the input bus.

Ports

Signal	Type	Size	Description
din	std_logic_vector	any	The input vector
dout	std_logic_vector	any	The output vector

Parameters

Generic	Type	Value	Description
Divisions	Integer	4	The number of equally-sized divisions of the input vector
Division Bit Width	Integer	2	The size of the divisions
Division Order	Comma-delimited Integers	3,0,2,1	The order of division-indices that determines the output vector
