LONDON – Cortus SA, foundry MagnaChip Semiconductor Corp. and design house Taegee Co. Ltd. have collaborated on the development of a 32-bit microntroller intended for touch-screen applications in tablet and laptop computers and smart phones.
The application-specific MCU (ASMCU) is based on the APS3 processor core from Cortus (Montpellier, France) and associated IP cores and software that enable touch and gesture recognition. This 32-bit microprocessor technology has been ported to Magnachip's 0.18-micron EEPROM manufacturing process technology by a design team at Taegee (Cheongju, South Korea). The jointly developed ASMCU will be manufactured for Taegee by MagnaChip foundry services (Cheongju, South Korea).
"The ASMCU developed for touch screen controllers is an excellent example of the products that will come out of this partnership. Our APS3 processor core is ideal for these applications with its low power, high performance and small core size," said Mike Chapman, president and CEO of Cortus, in a statement.
"The comprehensive training and simple interfaces provided by Cortus ensured very rapid integration helping us keep ahead of our aggressive schedules," said Channy Lee, president and CEO of Taegee, in the same statement. "The small silicon footprint and low power consumption features enabled us to meet our design goals and while providing the required processor performance. The APS3 will be a key feature in many of our future ASMCU designs."
The Cortus APS3 is a high performance 32-bit processor designed specifically for embedded systems. It offers 32-bit performance on a silicon foot-print that is the same as an 8-bit 8051, the company claimd. This contributes to a low power consumption, high code density and performance of up to 1.67-DMIPS/MHz.
A development environment for C and C++ is available together with embedded system peripherals, bus bridges and system support and functions such as cache and memory management units. The APS3 can be also used in a multi-core configuration.
Isn't 0.18 micron a tad old in these days, when
competition is moving to 90 nm embedded flash.
Anyway, the key to successful touchscreen design
is using the right touch algorithms.
Remains to be seen how this works.
Cool product 32-bit controller from a multi-dimensional cooperative effort. Let's hope it gets incorporated in volume in tablets, if the power dissipated is low enough, which it should be if it occupies the area of off-the-shelf popular 8-bit 8051.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
