VinChip Systems Inc. has released VinRZ5110 32bit RISC processor core, which it claims is the first 32bit processor to be developed in India. It has a DSP-centric instruction set and low gate count for low power consumption, the company said.

VinChip, which has a design center in Chennai, India, said the VinRZ5110 is suitable for use in applications including mass storage, automotive control, wireless devices and audio/video encoders and decoders. It is also suitable for FPGA-based embedded systems.

The core has been developed with on-chip debug logic based on OpenOCD, which also supports in-system programming via JTAG. An optional module, the VinSMDP, provides static and dynamic capture of debug data and in-system programming over USB 2.0 achieving speeds of 480Mbit/s. The VinSMDP can also multitask as a USB port for user tasks on the AHB bus.

The VinRZ5110 core has been ported to binutils 2.19, gcc 4.3.2, gdb 6.8 and Eclipse IDE. Support for virtual prototyping has been provided by the Open Virtual platform (OVP) and OVPsim simulator from Imperas Ltd. The instruction set simulator built using OVPsim enables development of embedded software ahead of the hardware production cycle.

Simon Davidmann, CEO of Imperas, said that the tools include providing the instruction set simulator using OVPs modeling technology, so that virtual platforms based on the VinRZ5110 can be built using both OVP and SystemC/TLM-2.0 simulators.
