the amount of data area available for shock prevention memory (SPM) will be as follows.
dB to +18 dB, common left and right setting. Record:
Assuming one 4 Mbit DRAM is used: 4 Mbit is 1 024 × 1 024 × 4 = 4 194 304 bits
Converting to bytes gives: 4 194 304/8 = 524 288 bytes
Working area of 2 KB: 1 024 × 2 = 2 048 bytes
Since 1 UTOC sector is 2 344 bytes, 9 sectors is: 2 344 × 9 = 21 096 bytes
The remaining area after subtracting work area and UTOC area will be:
524 288 - 2 048 -21 096 = 510 144 bytes
Dividing the remaining memory by the number of bytes in a sector (2 344 bytes) gives:
501 144/2 344 = 213.8 -> 213 sectors
Similar calculations give:
46 sectors/1 Mbit, 101 sectors/2 Mbits, 884 sectors/16 Mbits, 3 568 sectors/64 Mbits
