The Jaguar has five processors, which are contained in three chips. Two of
the chips are proprietary designs, nicknamed "Tom" and "Jerry". The third
chip is a standard Motorola 68000 used as a coprocessor. Tom and Jerry are
built using an 0.5 micron silicon process. With proper programming, all
five processors can run in parallel.
- "Tom"
- 750,000 transistors, 208 pins
- Graphics Processing Unit (processor #1)
- 32-bit RISC architecture (32/64 processor)
- 64 registers of 32 bits wide
- Has access to all 64 bits of the system bus
- Can read 64 bits of data in one instruction
- Rated at 26.591 MIPS (million instructions per second)
- Runs at 26.591 MHz
- 4K bytes of zero wait-state internal SRAM
- Performs a wide range of high-speed graphic effects
- Programmable
- Object processor (processor #2)
- 64-bit RISC architecture
- 64-bit wide registers
- Programmable processor that can act as a variety of different video
architectures, such as a sprite engine, a pixel-mapped display, a
character-mapped system, and others.
- Blitter (processor #3)
- 64-bit RISC architecture
- 64-bit wide registers
- Performs high-speed logical operations
- Hardware support for Z-buffering and Gouraud shading
- DRAM memory controller
- 64 bits
- Accesses the DRAM directly
- "Jerry"
- 600,000 transistors, 144 pins
- Digital Signal Processor (processor #4)
- 32 bits (32-bit registers)
- Rated at 26.6 MIPS (million instructions per second)
- Runs at 26.6 MHz
- Same RISC core as the Graphics Processing Unit
- Not limited to sound generation
- 8K bytes of zero wait-state internal SRAM
- CD-quality sound (16-bit stereo)
- Number of sound channels limited by software
- Two DACs (stereo) convert digital data to analog sound signals
- Full stereo capabilities
- Wavetable synthesis, FM synthesis, FM Sample synthesis, and AM
synthesis
- A clock control block, incorporating timers, and a UART
- Joystick control
- Motorola 68000 (processor #5)
- Runs at 13.295MHz
- General purpose control processor |

Programmable screen resolution. Horizontal resolution is
dependent on the amount of scanline buffer space given to the
"Tom" graphics processor. Maximum vertical resolution varies
according to the refresh rate (NTSC or PAL). Reportedly, a
stock Jaguar (without additional memory) running NTSC can
display up to 576 rows of pixels.
24-bit "True Color" display with 16,777,216 colors
simultaneously (additional 8 bits of supplimental graphics
data support possible)
Multiple-resolution, multiple-color depth objects (monochrome,
2-bit, 4-bit, 8-bit, 16-bit, 24-bit) can be used
simultaneously |
