Taiwan Semiconductor foundry United Microelectronics Corp. (UMC) has licensed the ARM946E core and the ARM1022E core. The licensing agreement allows UMC to offer an expanded portfolio to designers of ARM core-based devices, under the ARM foundry program.

According to the companies, the ARM7TDMI core and the ARM922T core can be manufactured on UMC's 0.13?m process technologies. The ARM7DTMI core is also production verified on UMC's 0.25?m and 0.18?m silicon while the ARM922T core is production verified in 0.18?m silicon.

The ARM946E macrocell is designed for embedded applications. It combines an ARM9E-S CPU with 8K instruction and data caches, instruction and data tightly-coupled memory (TCM) interfaces, a protection unit and an AMBA on-chip AHB interface. The companies say configurable instruction and data TCM memories allow the hardware to be tailored to the embedded application.

The ARM1022E macrocell incorporates the advanced ARM10E integer core, instruction and data caches, full-featured memory management unit, dual high-bandwidth 64-bit AMBA technology-compliant AHB interfaces and 16K/16K caches. It also includes an enhanced 16-by-32-bit multiplier capable of single-cycle MAC operations, 16-bit fixed-point DSP instructions to accelerate signal processing algorithms, and support for the Thumb 16-bit instruction set for high code density, explained UMC and ARM.
