Hombre chipset

Hombre is a RISC chipset for the Amiga designed by Commodore, intended as the basis of its next generation game machine called CD64.

Commodore also planned to build a 3D accelerator PCI card based on Hombre. Hombre was canceled along with the bankruptcy of Commodore International.

In 1993, Commodore International ceased the development of the AAA chipset and began to design a new 64-bit 3D graphics chipset based on Hewlett-Packard's PA-RISC architecture to serve as the new basis of the Amiga personal computer series. It was codenamed Hombre (pronounced "ómbre" which means man in Spanish) and was developed in conjunction with over an estimated eighteen-month period.

Hombre does not support any planar mode, nor any emulation for the legacy Amiga chipset or Motorola 680x0 CPU registers, so it was completely incompatible with former Amiga models. According to Hombre designer Dr. Ed Hepler, Commodore intended to produce an AGA Amiga upon a single chip to solve the backward compatibility issues. This single chip would include Motorola MC680x0 core, plus the AGA chipset. The chip could be integrated in Hombre based computers for backward compatibility with AGA software.

Hombre is based around two chips: a System Controller chip and a Display Controller chip.

The System Controller chip was designed by Dr. Ed Hepler, well known as the designer of the AAA Andrea chip. The chip is similar in principle to the chip bus controller found in Agnus, Alice, and Andrea of the Amiga chipsets. The chip features the following:

The Display Controller Chip was designed by Tim McDonald, also known as the designer of the AAA Monica chip. It is similar in principle to the Denise, Lisa, and Monica chips found on original Amigas. In addition, the chipset also supported future official or third party upgrades through extension for an external PA-RISC processor.
