HSB BUS Matrix (HMATRIX)

Purpose

The HSB Bus Matrix implements a multi-layer bus structure that enables parallel access paths between multiple High Speed Bus (HSB) masters and slaves in a system, which increases the overall bandwidth.

void hmatrix_get_slave_priority	(	enum hmatrix_slave_id	slave_id,
		hmatrix_prs *	p_prio
	)

Get priority for the specified slave access.

Parameters

[in]	slave_id	Slave index.
[in]	p_prio	Pointer to the priority register sets.

void hmatrix_init
