/*************************************************************************** 3do.c Driver file to handle emulation of the 3DO systems Hardware descriptions: Processors: - 32bit 12.5MHZ RISC CPU (ARM60 - ARM6 core) - Seperate BUS for video refresh updates (VRAM is dual ported) - Super Fast BUS Speed (50 Megabytes per second) - Math Co-Processor custom designed by NTG for accelerating fixed-point matrix operations (_not_ the ARM FPA) - Multitaking 32-bit operating system Resolution: - 640x480 pixel resolution - 16.7 million colors Two accelerated video co-processors: - 25MHZ clock rate (NTSC), 29.5MHZ clock rate (PAL) - Capable of producing 9-16 million real pixels per second (36-64 Mpix/sec interpolated), distorted, scaled, rotated and texture mapped. - able to map a rectangular bitmap onto any arbitrary 4-point polygon. - texturemap source bitmaps can be 1, 2, 4, 6, 8, or 16 bits per pixel and are RLE compressed for a maximum combination of both high resolution and small storage space. - supports transparency, translucency, and color-shading effects. Custom 16bit DSP: - specifically designed for mixing, manipulating, and synthesizing CD quality sound. - can decompress sound 2:1 or 4:1 on the fly saving memory and bus bandwidth. - 25MHz clock rate. - pipelined CISC architecture - 16bit register size - 17 seperate 16bit DMA channels to and from system memory. - on chip instruction SRAM and register memory. - 20bit internal processing. - special filtering capable of creeating effects such as 3D sound. Sound: - 16bit stereo sound - 44.1KHz sound sampling rate - Fully support Dolby(tm) Surround Sound Memory: - 2 megabytes of DRAM - 1 megabyte of VRAM (also capable of holding/executing code and data) - 1 megabyte of ROM - 32KB battery backed SRAM CD-ROM drive: - 320ms access time - double speed 300kbps data transfer - 32KB RAM buffer Ports: - 2 expansion ports: - 1 high-speed 68 pin x 1 AV I/O port (for FMV cartridge) - 1 high-speed 30 pin x 1 I/O expansion port - 1 control port, capable of daisy chaining together up to 8 peripherals Models: - Panasonic FZ-1 R.E.A.L. 3DO Interactive Multiplayer (Japan, Asia, North America, Europe) - Panasonic FZ-10 R.E.A.L. 3DO Interactive Multiplayer (Japan, North America, Europe) - Goldstar 3DO Interactive Multiplayer (South Korea, North America, Europe) - Goldstar 3DO ALIVE II (South Korea) - Sanyo TRY 3DO Interactive Multiplayer (Japan) - Creative 3DO Blaster - PC Card (ISA) =========================================================================== Part list of Goldstar 3DO Interactive Multiplayer - X1 = 50.0000 MHz KONY 95-08 50.0000 KCH089C - X2 = 59.0000 MHz KONY 95-21 59.0000 KCH089C (NTSC would use 49.09MHz) - IC303 BOB = 3DO BOB ADG 00919-001-IC 517A4611 - 100 pins - IC1 ANVIL = 3DO Anvil rev4 00745-004-02 521U5L36 - 304 pins - IC302 DSP = SONY CXD2500BQ 447HE5V - 80 pins - IC601 ADAC = BB PCM1710U 9436 GG2553 - 28 pins - X601 16.934MHz = 16.93440 KONY - IC101/102/103/104 DRAM = Goldstar GM71C4800AJ70 9520 KOREA - 28 pins - IC105/106/107/108 VRAM = Toshiba TC528267J-70 9513HBK - 40 pins - IC3 ROM = Goldstar [202M] GM23C8000AFW-325 9524 - 32 pins - IC4 SRAM = Goldstar GM76C256ALLFW70 - 28 pins - IC2 ARM = ARM P60ARMCP 9516C - 100 pins - IC6 = Philips 74HCT14D 974230Q - 14 pins - IC301 u-COM = MC68HSC 705C8ACFB 3E20T HLAH9446 - 44 pins ***************************************************************************/ #include "driver.h" #include "video/generic.h" #include "includes/3do.h" #include "devices/chd_cd.h" /* The 3DO has an ARM6 core which is a bit different from the current ARM cpu cores.
