C compiler for 8051 ups performance 55%

The HI-TECH C PRO C compiler for the Silicon Labs 8051 MCU family reduces interrupt latency, code size, and SRAM usage by dynamically optimizing context size and register coverage across all modules. The compiler is said to yield 55% more DMIPS/MHz and produce 30% to 50% smaller code.

The software uses “omniscient code generation” (OCG) technology that collects data on every register, stack, pointer, object, and variable declaration across the entire program to optimize register usage, stack allocations, and pointers. It defines address spaces for each pointer variable that is optimally efficient for the C8051 architecture, and it knows exactly how big the stack must be and where it will be located before the code is generated. A free trial version is available. ($1,195 available now.)
