8051 Highlights
8051 Development Tool Support
The Keil C51 Compiler and the Keil Linker/Locator provide optimum 8051
architecture support with the following features and C language extensions.
SFR and IDATA memory are located in the same address space but are
accessed through different assembler instructions
For extended devices, the memory layout provides a universal memory map
that includes all 8051-memory types in a single 16MByte address region
Fast interrupt service routines with two or four priority levels and up to 32-
vectored interrupts
Four register banks for minimum interrupt prolog/epilog
Bit-addressable space for efficient logical operations
128 Bytes of Special Function Register (SFR) space for tight integration of
on-chip peripherals. Some devices extend the SFR space using paging.
Low-power, high-speed devices up to 100 MIPS are available
Interrupt functions with register bank support are written directly in C
Bit and bit-addressable variables for optimal Boolean data type support
Compile-time stack with data overlaying uses direct memory access and
gives high-speed code with little overhead compared to assembly
programming
Reentrant functions for usage by multiple interrupt or task threats
Generic and memory-specific pointers provide flexible memory access
Linker Code Packing gives utmost code density by reusing identical program
sequences
Code and Variable Banking expand the physical memory address space
Absolute Variable Locating enables peripheral access and memory sharing
