Ultra low power, high-performance DSP / controller RISC core

Overview

Based on its long standing expertise in ultra low power processors for the Swiss watch industry, CSEM now offers three architectures in its icyflex family of ultra low-power processors:

icyflex2 for control type applications with power consumptions as low as 6 uW/MHz

icyflex1 for a mix of control and DSP-type applications

icyflex4 for a scalable architecture capable of some control and massive parallelism for DSP-type applications

Key Features

  • Customizable architectures:
    • All 3 processors are available as VHDL soft blocks with multiple parameters (bus widths, stack size, optional blocks) so you only integrate the part of the processor you use.
  • Configurable architectures:
    • The processors can be configured at run time to add new addressing modes and new instructions to reduce the number of cycles for individual algorithms.
  • High parallelism:
    • The processors feature powerful datapaths (up to 36 MAC) and high bandwidth to registers and memory for maximum throughput per instruction, or clock cycle.
  • Software development kit (SDK):
    • World-class GNU tool suite (compiler, assembler, debugger, cycle accurate instruction set simulator, ...) with plugin for the Eclipse IDE.
  • Hardware development kit (HDK):
    • Plug-and-play motherboard for development on System-on-Chip (SoC) and on FPGA to reduce time to market.
  • Quality:
    • The processors are designed for testability and support On-Chip-Debug through a JTAG interface. Silicon proven.

Benefits

  • High performance processors with best in class energy efficiency
  • World-class environment for software development (GNU & Eclipse)
