SMJ320 is a trademark of Texas Instruments Incorporated.
This data sheet provides design documentation for the SMJ320C25 and the SMJ320C25-50 digital signal processor (DSP) devices in the SMJ320? family of VLSI digital signal processors and peripherals. The SMJ320 family supports a wide range of digital signal processing applications such as tactical communications, guidance, military modems, speech processing, spectrum analysis, audio processing, digital filtering, high-speed control, graphics, and other computation-intensive applications.
Differences between the SMJ320C25 and the SMJ320C25-50 are specifically identified, as in the following paragraph and in the parameter tables on pages 18 through 24 of this data sheet. When not specifically differentiated, the term SMJ320C25 is used to describe both devices.
The SMJ320C25 has a 100-ns instruction cycle time. The SMJ320C25-50 has an 80-ns instruction cycle time. With these fast instruction cycle times and their innovative memory configurations, these devices perform operations necessary for many real-time digital signal processing algorithms. Since most instructions require only one cycle, the SMJ320C25 is capable of executing 12.5 million instructions per second. On-chip data RAM of 544 16-bit words, on-chip program ROM of 4K words, direct addressing of up to 64K words of external data memory space and 64K words of external program memory space, and multiprocessor interface features for sharing global memory minimize unnecessary data transfers to take full advantage of the capabilities of the instruction set.

【PCB設(shè)計必備】31條布線技巧2023-08-03 08:09
相信大家在做PCB設(shè)計時,都會發(fā)現(xiàn)布線這個環(huán)節(jié)必不可少,而且布線的合理性,也決定了PCB的美觀度和其生產(chǎn)成本的高低,同時還能體現(xiàn)出電路性能和散熱性能的好壞,以及是否可以讓器件的性能達到最優(yōu)等。在上篇內(nèi)容中,小編主要分享了PCB線寬線距的一些設(shè)計規(guī)則,那么本篇內(nèi)容,將針對PCB的布線方式,做個全面的總結(jié)給到大家,希望能夠?qū)︷B(yǎng)成良好的設(shè)計習慣有所幫助。1走線長度1693瀏覽量 -

千萬不要忽略PCB設(shè)計中線寬線距的重要性2023-07-31 22:27
想要做好PCB設(shè)計,除了整體的布線布局外,線寬線距的規(guī)則也非常重要,因為線寬線距決定著電路板的性能和穩(wěn)定性。所以本篇以RK3588為例,詳細為大家介紹一下PCB線寬線距的通用設(shè)計規(guī)則。要注意的是,布線之前須把軟件默認設(shè)置選項設(shè)置好,并打開DRC檢測開關(guān)。布線建議打開5mil格點,等長時可根據(jù)情況設(shè)置1mil格點。PCB布線線寬01布線首先應(yīng)滿足工廠加工能力,1795瀏覽量 -
