AMD unveils MIPS system-on-chip with built-in LCD controller

Apr 8, 2002 — by LinuxDevices Staff — from the LinuxDevices Archive — 3 views

AMD today unveiled the latest fruit of its recent acquisition of Alchemy Semiconductor: the Au1100 processor, a MIPS-based system-on-chip that targets non-PC mobile internet apps such as webpads, telematics, and PDAs. The device contains a RISC processor which executes the MIPS32 instruction set, and is designed for a combination of high performance and low power. Power dissipation is said to be less than 0.25 watt at a 400 MHz clock rate. The highly integrated device includes an impressive list of built-in functions, including memory controllers, an LCD controller, 10/100 Ethernet Controller, USB Host and Device controllers, three UARTs, a PCMCIA interface, and up to 48 general purpose I/Os. The Au1100 supports a variety of embedded operating systems, including Windows CE, Linux, and VxWorks.

Further details on the Au1100 are available here.

Together with the earlier members of the Alchemy Au1xxx family, the new highly integrated, high performance, and low power RISC processor puts AMD in a strong position to compete with Intel's StrongARM and XScale product families. AMD acquired Alchemy Semiconductor in February of this year.
