It is predicted that demand for voice-control applications will grow dramatically in the market, driven by the telephone market. Telephones will be more controlled by voice commands. Other areas of application include toys and handheld devices such as calculators, voice-controlled security systems, home appliances and on-board equipment (stereo, Windows, environmental controls, headlights and navigation control). This paper introduces the design of speech recognition

The installation is very simple (thanks to the Debian Ubuntu Strong warehouse):$ sudo apt-get install as31 emu8051 dis51 Cycfx2progOh, remember that Mr. Mao once taught us to "drink water do not forget to dig well people", we look at the developers of these tools:A.

There are many books which say that variables are best to assign initial values. But why should the initial value be? What kind of accident might happen if we don't assign an initial value? The following is my analysis of the implementation of the 51 single-chip microcomputer for the compiler to see the Mcu,keil.It is well known that variables are stored in RAM, lost after power-down, and are all 0 by default after power-up. Then the value of the vari

Recently in the toss Raspberry Pi, at that time also did not pay attention to, look at the price, bought Mercury network MW150US Ultra-small 150M wireless USB card. But the tragedy was to use iwconfig and not recognize the wireless card But with lsusb words can see MW150US with is Rtl8188eu chip, search on the network, finally found a solution 1. first download the latest Linux kernel for compiling and installing, refer to Http://www.raspberrypi.org/d

Recently, a lot of time in Arm9 s3c2410a ran a NetBSD3.0. Refer to some information on the Internet, especially a Korean website (do not understand Ah, Shingwen), I recorded the process in detail, to the AIDS enthusiasts. The whole process is very simple! I think the reason is that NetBSD is a complete OS. The following is a detailed description of the process (due to NetBSD itself excellent build framework, so the steps are not much, I can do is to say more details, say wordy, ah ~) Producti

3. Interrupt Controller Driver In the Linux kernel, individual device drivers can simply invoke Request_irq (), ENABLE_IRQ (), DISABLE_IRQ (), local_irq_disable (), local_irq_enable () such as General API complete interrupt application, enable, prohibit and so on function. When porting Linux to a new SOC, the chip vendor needs to provide low-level support for that part of the API. The implementation of Local_irq_disable (), Local_irq_enable () is in

Contact SCM has a few years of time, has been focused on how to write some applications on a single chip microcomputer, how to start the knowledge of little, ashamed ashamed ... Today, I have to tidy up a bit, deepen the understanding of the SCM, such as why the definition of the data area of the variable restart the initial value of 0. When the MCU is powered on, it will execute startup. The instructions for the A51 file, I analyzed the instructions

are parity bits (1/0). The sum of the number of 1 in the data and the number of the test bit 1 should be odd at parity, and the number of 1 in the data and the number of checksum digits 1 should be even when parity. When a character is received, the number of 1 is validated, and if the character is inconsistent, an error occurs during the transfer of the data. Code and checksum The sender sums the data blocks (or each byte xor), resulting in a byte of the checksum character (checksum) appended
