MI_UnpackBits


C Specification

#include <nitro/mi.h>

void MI_UnpackBits( 
            const void*    srcp, 
                  void*    destp, 
    MI_UnpackBitsParam*    paramp );

Description

This function expands data that has been packed with 0-fixed bits. The destination address must be aligned to a 4-byte boundary.

This is the MI_UnpackBitsParam structure.

The number of source data bytes u16.
The number of bits in one source data (u16:8).
The number of bits in one destination data (u16:8).
The offset that is to be added to the source data (u32:31).
A flag that indicates whether to add an offset to 0 data (u32:1).

Internal Operation

This processes with the CPU without using a system call or DMA.

Arguments

srcp

The source address where compressed data is stored

destp

The destination address for expansion

paramp

The address for MI_UnpackBitsParam structure data

Return Values

None
