Features
Powerful Optimization Functions
The CA850 comes with "powerful optimization functions" that make the most of the device's performance fea-
tures. Users can select among six optimization levels, and can even set optimization levels for individual sources.
Functions Optimized for Embedded Systems
The CA850 provides functions optimized for development of the embedded systems.
O Functions related to size reduction of ROM/RAM used and acceleration of execution speed
Complies with ANSI-C standard for C language programming
Includes powerful optimization functions
Provides functions optimized for embedded systems
Provides multiple utilities
Selection of register mode (software register bank function)
Run-time library is used for processing of function prologues and epilogues
Structure/union packing function
Register allocation function for external variables
Code size is reduced by library functions that can be called both when saving to registers and when restoring from
This packing function fills holes between members of structures or unions due to alignment, which reduces code
Setting a limit on the number of registers that can be used by the compiler (either 22 or 26 registers) reduces the
When in 22 or 26 register mode, the user can freely allocate external variables to any usable register and can
