In general, you should simply ignore the ".n" at the end of instructions. The Xtensa implements SPARC like register windows on subroutine Only the stores S32I and S32I.N can access InstRAM. Table 3–13 shows the loads in the Core Architecture. Table 3–13. Store Instructions Instruction Format Compound compare and branch instructions Funnel shift Left shift & add / subtract Load / store at constant offset movi movin nop.n ret.n , retw.n s32i.ENTRY instruction primarily does two things: 1. Allocates the stack frame for the function and sets the stack pointer. 2. Moves/rotates the register window by n S32I.N. RRRN. Store 32 bits, 4-bit offset. 1. These instructions are fully described in Chapter 6, "Instruction Descriptions" on page 243. SOC designers can create single-cycle TIE instructions that draw operands from N} The firstline of this example code declares a new instruction length Xtensa Instruction Set Architecture (ISA) Reference Manual ASSEMBLER GUIDE.
