Korea's Dongbu chooses EnSilica RISC processor

Dongbu HiTek, a foundry in South Korea, has licensed the eSi-1600 embedded RISC processor of design house EnSilica Ltd.

The eSi-1600 is a 16bit CPU core designed for integration into ASIC and FPGA designs. It belongs to a configurable family of processor cores.

Dongbu HiTek chose the eSi-1600 following evaluation against other established, small-footprint embedded RISC processors targeted at mixed-signal and SoC applications, Wokingham, England-based EnSilica said.

Dongbu HiTek's application code benchmarks showed that EnSilica's eSi-1600 had a 20 percent lower gate count, and that with the addition of a single custom instruction, it was also 36 percent faster.

The eSi-RISC architecture is scalable from 16- to 32bits, starting from as few as 8.5k gates. It utilizes the GNU optimizing C/C++ compiler and Eclipse IDE for software development, and supports debugging on the target through a JTAG interface and hardware breakpoints. The development suite is common to both 16bit and 32bit processors.

"The fully integrated processor sub-system, including memories, peripherals and timers, will greatly reduce design and verification time. Furthermore, EnSilica's flexible licensing model makes the use of eSi-RISC very attractive for cost-sensitive, high volume designs," said Jinseok Koh, a director with Dongbu HiTek, in a statement issued by EnSilica.
