 Featuring a total of eight processors the Saturn 's main central processing units are two Hitachi SH @-@ 2 microprocessors clocked at 28 @.@ 6 MHz and capable of 56 MIPS . The system contains a Motorola 68EC000 running at 11 @.@ 3 MHz as a sound controller , a custom sound processor with an integrated Yamaha FH1 DSP running at 22 @.@ 6 MHz capable of up to 32 sound channels with both FM synthesis and 16 @-@ bit PCM sampling at a maximum rate of 44 @.@ 1 kHz , and two video display processors , the VDP1 ( which handles sprites , textures and polygons ) and the VDP2 ( which handles backgrounds ) . Its double @-@ speed CD @-@ ROM drive is controlled by a dedicated Hitachi SH @-@ 1 processor to reduce load times . The Saturn 's System Control Unit ( SCU ) , which controls all buses and functions as a co @-@ processor of the main SH @-@ 2 CPU , has an internal DSP running at 14 @.@ 3 MHz . The Saturn contains a cartridge slot for memory expansion , 16 Mbit of work random @-@ access memory ( RAM ) , 12 Mbit of video RAM , 4 Mbit of RAM for sound functions , 4 Mbit of CD buffer RAM and 256 Kbit ( 32 KB ) of battery backup RAM . Its video output , provided by a stereo AV cable , displays at resolutions from 320 × 224 to 704 × 224 pixels , and is capable of displaying up to 16 @.@ 77 million colors simultaneously . Physically , the Saturn measures 260 mm × 230 mm × 83 mm ( 10 @.@ 2 in × 9 @.@ 1 in × 3 @.@ 3 in ) . The Saturn was sold packaged with an instruction manual , one control pad , a stereo AV cable , and its 100V AC power supply , with a power consumption of approximately 15W .
