The eSi-1600 is a compact 16-bit RISC processor core engineered for efficiency and low power. It is well-suited for control applications that typically utilize 8-bit systems, boasting reduced system costs akin to those smaller CPUs, yet providing significantly higher performance. Its architecture allows for reduced clock cycles per application, resulting in substantial power savings, which is particularly beneficial in resource-constrained environments.
This processor core features a 5-stage pipeline that enhances its ability to achieve higher clock frequencies, even in matured semiconductor processes. It includes a rich set of arithmetic instructions, offering capabilities like full 32-bit multiplication and accumulations, bit manipulation, and optional application-specific instructions. This versatility is further illustrated by the optional support for user and supervisor operating modes, reflecting its adaptability across multiple application scenarios.
Besides typical features such as JTAG or serial debug capabilities, the eSi-1600 supports a wide array of peripherals through standard AMBA interconnects. Its instruction set achieves exceptional code density by utilizing intermixed 16 and 32-bit instructions. The processor's silicon-proven design, combined with extensive toolchain support, makes it a highly reliable choice for low-cost embedded applications.
