IAR Embedded Workbench for 8051 - Library Source 8.2

IAR Embedded Workbench for 8051 – Library Source is an optional add-on from IAR Systems that provides the complete source code for the C runtime libraries used by the IAR 8051 toolchain. With access to the library source, you can rebuild and tailor the runtime to match your device, memory model, and application needs—reducing footprint, enhancing performance, and increasing transparency.

Key capabilities:

• Rebuild the IAR C runtime libraries to fit specific 8051 memory models and device variants.
• Retarget low-level I/O (for example, printf/scanf) to UART, SPI, or custom drivers.
• Enable or remove features such as floating-point and locale support to optimize code size.
• Adjust heap/stack use, startup behavior, and system initialization for tighter control.
• Step into library functions during debugging with C-SPY for deeper insight and verification.
• Facilitate code review and certification processes by making library behavior fully visible.

Designed for teams that need precise control over runtime behavior and resource usage on 8051-based systems, the Library Source integrates seamlessly with IAR Embedded Workbench for 8051. A compatible IAR Embedded Workbench for 8051 license is required.
