| //// Function Name : impeg2_memset_8bit_8x8_block_av8() |
| //// |
| //// Detail Description : This routine intialises the Block matrix buffer contents to a |
| //// particular Value. This function also assumes the buffer size |
| //// to be set is 64 Bytes fixed. It also assumes that blk matrix |
| //// used is 64 bit aligned. |
| //// |
| //// Inputs : pi2_blk_mat : Block Pointer |
| //// u2_val : Value with which the block is initialized |
| //// |
| //// Registers Used : v0 |
| //// |
| //// Stack Usage : 64 bytes |
| //// |
| //// Outputs : Block Matrix Iniliazed to given value |
| //// |
| //// Return Data : None |
| //// |
| //// Programming Note : This implementation assumes that blk matrix buffer |
| //// is 128 bit aligned |
