Abstract: A microcontroller apparatus is provided with an instruction set for manipulating the behavior of the microcontroller. The apparatus and system is provided that enables a linearized address space that makes modular emulation possible. Direct or indirect addressing is possible through register files or data memory. Special function registers, including the Program Counter (PC) and Working Register (W), are mapped in the data memory. An orthogonal (symmetrical) instruction set makes possible any operation on any register using any addressing mode. Consequently, two file registers to be used in some two operand instructions. This allows data to be moved directly between two registers without going through the W register. Thus, increasing performance and decreasing program memory usage.

Abstract: A device, system and method for providing access to user memory in emulator systems. The emulator system contains an emulator system memory, a user system memory and an emulator device. The emulator device operates in a mode where program execution instructions originate in the emulation memory while read and write instructions target the user memory. Logic included in the emulator chip directs the read and write memory accesses to the user memory while instructions are fetched from the emulator memory.
