Abstract
The present invention relates to a slot type universal multiple chip digital signal processing unit (DSP) hard ware device. The device comprises a sequence control circuit and a motherboard which is provided with a stack memory, wherein the motherboard is provided with at least more than two digital signal processing unit (DSP)expansion slots, and DSPs in each slot are arranged on the same bus in a serial interface mode.
Description
The present invention relates to a kind of consumer electronics product, especially a kind of insertion slot type, universal, multiple chip and digital signal processing unit (DSP) hard ware device.
Usually to complicated digital information processing system, a slice digital signal processing unit (DSP) can not satisfy the requirement of work far away, the design of multi-disc DSP is absolutely necessary, the multi-disc dsp system that uses all is that design is printed on the sheet at one at present, all round circuit by necessity carries out collaborative work, when its disadvantage is that the initial stage tests, be difficult to estimate the complexity of algorithm, promptly can not determine out the number of the DSP of use, then in the design of circuit board, get certain having more than needed, will inevitably cause unnecessary waste so.
The objective of the invention is to utilize the slot mode, can increase or reduce the quantity of DSP at any time, add as required and subtract the DSP unit, accomplish flexible for avoiding waste.
The object of the present invention is achieved like this, a kind of insertion slot type, universal, multiple chip and digital signal processing unit (DSP) hard ware device, comprise that a sequential control chip, is provided with the digital signal processing unit motherboard of stacked memory, wherein: the digital signal processing unit expansion slot more than at least two is set on described motherboard, and equal one of plug-in mounting digital signal processing unit chip independently in each expansion slot, the connected mode with serial line interface between each digital signal processing unit adjacent one another are is arranged side by side on same bus.That is to say that each DSP has the minimum system that it works alone, each subsystem has a plug; Motherboard then is the mother system of each DSP, has Multirow socket on the mother system, because the cabling of a plurality of DSP is identical, so the mode of employing bus, each subsystem all can be inserted in arbitrarily on the slot.Like this, just can add the number of DSP according to the complexity of algorithm arbitrarily.
Owing to adopted above-mentioned scheme, purpose good effect of the present invention is conspicuous: the disadvantage that design circuit was underestimated before insertion slot type, universal, multiple chip DSP hardware system can be avoided, arbitrarily increase or reduce the number of DSP, reduced cost as much as possible, and handsome in appearance, change conveniently freely.
The subsystem that realization designs and produces has versatility, and each subsystem can be finished function separately, and after finishing when subtask, subsystem has affluence, can continue to employ next time and use, and accomplishes fully and does not waste.
After having designed and produced subsystem and general mother system, can finish the work of various programs.If it is complicated at the algorithm that beginning is write, need to use more DSP, both subsystems, and along with the carrying out of working, this algorithm has carried out more optimal modification, and no longer need so many DSP this moment, just can extract the parton system, task still can be carried out smoothly, and these subsystems just can be waited until next time and be used.
Below in conjunction with drawings and Examples in detail the present invention is described in detail again.
Fig. 1 is the structural representation of the insertion slot type, universal, multiple chip digital signal processing hardware device that the present invention relates to.
By Fig. 1, of the present inventionly relate to a kind of insertion slot type, universal, multiple chip and digital signal processing unit (DSP) hard ware device, comprise that a sequential control chip, is provided with the digital signal processing unit motherboard of stacked memory, wherein: the digital signal processing unit expansion slot more than at least two is set on described motherboard, and equal one of plug-in mounting digital signal processing unit chip independently in each expansion slot, the connected mode with serial line interface between each digital signal processing unit adjacent one another are is arranged side by side on same bus.Above-mentioned each digital signal processing unit chip that is arranged on the same motherboard, the input end of two chips that it is adjacent, output terminal are respectively the data output end of prime chip and the data input pin of back level chip.
In this scheme, DSP is used to finish operation of data, i.e. the physics realization of algorithm, and auxiliary logical circuit then is used to realize the generation of handling up of data and sequential.Like this benefit of making be DSP can " attentively " in algorithm itself, reduce the time overhead of data of handling up, thereby reduce the quantity of DSP, simplify the dsp software design, the strong point of logical circuit is that speed is fast, be suitable for finishing such as frequency division, the simple work that repeats such as displacement, thereby to finish handling up of data with it be only.Auxiliary logical circuit also will be finished tasks such as control, demonstration and program loading in addition.
Exchanges data between the DSP can adopt multiple mode, for example bus arbitration, dual port RAM, parallel transmission, serial transmission etc.According to the DSP characteristics of Motorola, adopt the mode of serial transmission in this programme.The hardware resource that this mode is used is economized most, and the operation time that takies DSP is few.
The problem of data sync is actually the problem of the coordination between the DSP, and just DSP does not conflict with computing when Data transmission mutually.Adopt the mode of interrupting to pass into data in this programme, when Data transmission, adopt handshake to guarantee the accurate of data transmission.
The data of a plurality of DSP go into, go out all by stacked memory in this programme, and purpose is that handling up of data set up buffering, reads and writes data to make things convenient for DSP.Each DSP delivers to next adjacent DSP with its data of having handled when new data enters DSP1 and handles, also is the last source that adjacent DSP is its new data of each DSP.And sequential control circuit produce the required various sequential (as reading and writing clock, synchronizing pulse etc.) of DSP and stacked memory work and with many DSP between communicate by letter, control circuit together coordinates the work between each DSP.Connect by high speed serial port between each DSP, in order to the transmission data, the user can increase and decrease the quantity of DSP easily according to the size of operand like this.
