MI_UncompressLZ*


C Specification

#include <nitro/mi.h>

void MI_UncompressLZ8( 
    const void*     srcp, 
          void*     destp );

void MI_UncompressLZ16( 
    const void*     srcp, 
          void*     destp );

Description

This function expands LZ77 compressed data and writes it to 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_UncompressLZ8() writes in 8-bit units. You cannot expand directly in VRAM.

MI_UncompressLZ16() writes in 16-bit units. Although you can expand in DTCM or main memory, this function is slower than MI_UncompressLZ8. For compressed data, set a matching character string as one that has been found at least 2 bytes before.

Internal Operation

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

Argument

srcp The source address where LZ77 compressed data is stored
destp The destination address where it will be expanded

Return Values

None
