Embodiment Construction

[0008] The structure and working mode of this automatic machine unit are specifically described below in conjunction with accompanying drawing:

[0009] Such as figure 1 , the automaton of the present invention can have:

[0010] · Data input and output,

[0011] · Logic inputs and outputs,

[0012] · The output of the next state,

[0013] ·Numerical state saved internally, such as counting value, etc.

[0014] Such an automaton unit as figure 1 shown. Automata can have multiple numeric and logical input variables. figure 1 The upper left corner is the logic input (Boolean inputs), and the lower right corner has the digital input (number inputs). There is a row of selectors above the digital input, which are used to select input variables for the arithmetic units (OP1, OP2, ..., OPn) above it. These selectors are reconfigurable. Each selector can choose one of 4-6 variants.

[0015] The arithmetic unit operates on the input data, and the result is sent to the upper b...

Abstract

The invention discloses a controller structure of signal processing hardware in a novel data stream DSP (digital signal processor). The controller structure is mainly an input-output control group consisting of an algorithmic logic extension automaton (algorithmic FSM) and consists of an extension automaton unit; the condition of state transition can be an algorithmic logic expression; and an output is also the result of the algorithmic logic expression. The extension automaton unit comprises: (1) all selectors, (2) all operators (OP1, ..., OPn), (3) all comparators (CMP1, ..., CMPk), and (4) a logic operator. All the units can be reconstructed. The automaton unit is specially designed for the hardware programming of a bottom layer and is subjected to optimization design aiming at a typical image and a video processing algorithm. The controller structure has extremely high execution efficiency.

Description

1. Technical field [0001] The invention relates to a programmable controller structure of signal processing hardware in a novel data flow DSP. To be precise, it involves a control module structure of a unique data flow reconfigurable cell array machine. It belongs to the field of integrated circuit design. 2. Background technology [0002] Current consumer electronic devices require huge DSP, video / audio processing capabilities. Currently, the only hardware options for hardware engineers to implement their algorithms are ASICs, off-the-shelf programmable digital signal processors, and FPGAs. The use and functions of ASIC are fixed, and customers cannot make any changes, so they cannot meet the different needs of various customers. But hardware ASIC has the advantages of low power consumption, high performance, low cost, and high yield. But their disadvantages are high design cost and long design cycle; for programmable DSP represented by TI's DSP, customers need a group ...
