MI_UncompressRL*


C Specification

#include <nitro/mi.h>

void MI_UncompressRL8( 
    const void*    srcp, 
          void*    destp );

void MI_UncompressRL16( 
    const void*    srcp, 
          void*    destp );
    

Description

This function expands run length compressed data, and writes it in the specified memory region. The source address must be aligned to a 4-byte boundary.

When the size of the compressed data is not a multiple of four, the data size must be adjusted by padding the size with zeros.

MI_UncompressRL8 writes in 8-bit units. You cannot expand directly in VRAM.

MI_UncompressRL16 writes in 16-bit units. Although you can expand in DTCM or main memory, this function is slower than MI_UncompressRL8.

Internal Operation

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

Arguments

srcp

The source address where run length compressed data is stored.

destp

The destination address for expansion.

Return Values

None.
