Title

CPU AGB - ARM 01171

Subject

Primary CPU for the Game Boy Advance

Description

9 memory areas: System ROM, CPU External Work RAM, CPU Internal Work RAM, Register memory, Palette RAM, OBJ VRAM, BG VRAM, OAM and CART ROM.

32bit RISC CPU, 16.78MHz, 32bit opcodes

According to ARM: "The ARM7TDMI core has a Von Neumann architecture, with a single 32-bit data bus carrying both instructions and data. Only load, store, and swap instructions can access data from memory."

According to UNIX:
- "It is an ARM7 processor"
-"It includes the Thumb 16-bit compressed instruction set"
-"It has on-chip Debug support"
-"It has an enhanced 32-bit x 8 Multiplier, with 64-bit result"
-"It has EmbeddedICE hardware that supports on-chip breakpoints and watchpoints"

I could not locate a specific factory for this component, so I placed it in Kyoto, Japan, where the Nintendo headquarters are located. The text on the chip specifies JAPAN, and I found out in my research that ARM processors are made all throughout the world by a myriad of companies, so I thought that this was a reasonable guess.

ARM (Advanced RISC Machine) is a general family of instruction set guidelines for computing chips. RISC = Reduced Instruction Set Computing. ARM applies to both 32-bit and 64-bit processors and requires far fewer transistors than standard Complex Instruction Set Computing processors.
