SELECTAB

SELECTAB - 2 channel multiplexer

Usage:

SELECTAB A B SEL

Inputs:

A, B	data input A and B (number or vector, see I/O configuration table)
SEL	selection and/or condition

Outputs:

Y	output for selected data input (same type as A)

Function:

This atom implements a direct or conditional 2-channel multiplexer controlled via the input SEL. The input SEL is checked at the beginning of each evaluation cycle.

Table 23: Multiplexer method selected by input SEL

value of SEL	value copied to Y
0 or A	input A is copied to output Y
1 or B	input B is copied to output Y
2 or MINIMUM	Min(A, B) is copied to Yfor vectors, the operation is applied element by element!
3 or MAXIMUM	Max(A, B) is copied to Yfor vectors, the operation is applied element by element!

Table 24: Possible I/O configurations:

type of input A	type of input B	type of output Y	assignment
Number	number	number	Y is set to A or B
Vector	number	vector	Y[i] is set to A[i] or B
vector	vector	vector	Y[i] is set to A[i] or B[i]
