The present invention relates generally to processor instruction sets and, more particularly, to an instruction set for processing micro-controller type instructions and digital signal processor instructions from a single instruction stream.
Processors, including microprocessors, digital signal processors and microcontrollers, operate by running software programs that are embodied in one or more series of instructions stored in a memory. The processors run the software by fetching the instructions from the series of instructions, decoding the instructions and executing them.
In addition to program instructions, data is also stored in memory that is accessible by the processor. Generally, the program instructions mochine oa binary oa 0x2000 data by accessing mochine oa binary oa 0x2000 in memory, modifying the data and storing the modified data into memory.
The instructions themselves also control the sequence of functions that the processor performs and the order in which the processor fetches and executes the instructions. For example, the order for fetching and executing each instruction may be inherent in the order of the instructions within the series.
Alternatively, instructions such as branch instructions, conditional branch instructions, subroutine calls and other flow control instructions may cause instructions to be fetched and executed out of the inherent order of the instruction series. The program instructions that comprise a software program are taken from an instruction set that is designed for each processor.
The instruction set includes a plurality of instructions, each of which specifies operations of one or more functional components of the processor. The instructions are decoded in an instruction decoder which generates control signals distributed to the functional components of the processor to perform the operation s specified in the instruction.

It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention mochine oa binary oa 0x2000 the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. In order to describe the instruction set and its relationship to a processor for executing the instruction set, an overview of pertinent processor elements is first presented with reference to FIGS.
The overview section describes the process of fetching, decoding and executing program instructions taken from mochine oa binary oa 0x2000 instruction set according to embodiments of the present invention.
The processor may be any type of processor including, for example, a digital signal processor DSPa microprocessor, a microcontroller or combinations thereof. Moreover, the processor and the external devices may together comprise a stand alone system. The buswhich may include one or more common buses, communicates data between the units as shown.
The program memory stores software embodied in program instructions for execution by the processor In addition, the program memory may be supplemented with external nonvolatile memory as shown to increase the mochine oa binary oa 0x2000 of software available to the processor Alternatively, the program memory may be volatile memory which receives program instructions from, for example, an external non-volatile memory When the program memory is nonvolatile memory, the program memory may be programmed at the time of manufacturing the processor or prior to or during implementation of the processor within a system.
In the latter scenario, the processor may be programmed through a process called in-line serial programming. Coupled to the program memory and the bus is the program counter and loop control unit The program counter and loop control unit includes a program counter register not shown which stores an address of mochine oa binary oa 0x2000 next instruction to be fetched. During normal instruction processing, the program counter register may be incremented to cause sequential instructions to be fetched.
Alternatively, the program counter value may be altered by loading a new value into it via mochine oa binary oa 0x2000 bus The new value may be derived based on decoding and executing a flow control instruction such as, for example, a branch instruction.
In addition, the loop control portion of the program counter and loop control unit may be used to provide repeat instruction processing and repeat loop control as further described below. As part of this process, the execution units may retrieve one or two operands via the bus and store the result into a register or memory location within the data memory The execution units may include an arithmetic logic unit ALU such as those typically found in a microcontroller.
The execution units may also include a digital signal processing engine, a floating point processor, an integer processor or any other convenient execution unit. A preferred embodiment mochine oa binary oa 0x2000 the execution units and their interaction with the buswhich may include one or more buses, is presented in more detail below with reference to FIG.

The following sequence of events may comprise, for example, the execute instruction cycle for a single operand instruction: The following sequence of events may comprise, for example, the execute instruction cycle for a dual operand instruction using a data pre-fetch mechanism.
These instructions pre-fetch the dual operands simultaneously from the X and Y data memories and store them into registers specified in the instruction. They simultaneously allow instruction execution on the operands fetched during the previous cycle. The DSP engine executes various instructions within the instruction set according to embodiments of the present invention. These elements and others that are discussed below with reference to FIG.
