eASIC Corporation and EnSilica announced the immediate availability of 16-bit (eSi-1600) and 32-bit (eSi-3200) soft processor cores. The eSi-1600 and the eSi-3200 are based on an EnSilica's eSi-RISC highly versatile microprocessor architecture that can be optimized by application through extensive configuration options and custom instructions. The eSi-RISC architecture provides the flexibility to define a range of hardware functions that minimize silicon area.

On-chip memory requirements are reduced by inter-mixed 16-bit and 32-bit instructions, resulting in high code density without compromising performance. eSi-RISC utilizes the industry standard GNU optimizing C/C++ compiler and Eclipse IDE for rapid software development, and supports efficient debugging through a JTAG interface and hardware breakpoints. The eSi-RISC architecture also supports instruction and data cache options for both the 16 and 32-bit processor and a MMU, Floating Point Unit and DSP extensions.
