At present, the domestic market common arm has NXP (Philips), Samsung, Atmel, TI, Adi, etc., according to user requirements and application areas, can be selected from the following aspects:1, Speed (general application): ARM7 's main clock is 20~133M,ARM9 for 100~233M,ARM10 up to 700M, if the speed requirements are higher, you can also use multi-core arm, such as Minspeed company's arm series of chips.2, Memory (general application): General arm with
Today, I accidentally used a Samsung 5.5-inch mobile phone to watch the ecshop Mall. Oh, it's so ugly. I used a simulated tablet to access it. What's worse, I used the mobile phone version of ecshop, but there is no suitable tablet size, so if you look at it on the tablet, it is best to use the web version of the computer, under the ecshop root directory index. in the php file, a jump is made to determine whether the mobile phone version is accessed, but the process is not very good, so
CCD Dr is written as follows: detector array: Single-Chip non-spliced vhd CCD detector, size: 43x 43 cm (17*17 ). This description can be understood as the size of the core detector component of the CCD Dr is 17*17. In fact, their detector's front-end iodine part is 17*17, but after a layer-by-layer conversion (CCD Dr is not a direct imaging, the final size of the detector CCD is only a little larger than a circle of coins. The most direct consequence of the Small Size Detector in detecting lar
