LSI邏輯公司的低成本語音處理器
目前，對(duì)適合家庭和小辦公室應(yīng)用的Voice over IP (VoIP)的解決方案的需求在不斷增長(zhǎng)。市場(chǎng)需求的是非常低成本的兩到四路語音話路。LSI邏輯公司的解決方案能夠以非常低的成本卻非常有效地處理高達(dá)四路的語音話路，并且可在電話適配器、寬帶調(diào)制解調(diào)器以及路由器、網(wǎng)關(guān)中得到廣泛應(yīng)用。這些產(chǎn)品的基本組成部分包括語音處理子系統(tǒng)、主處理器、網(wǎng)絡(luò)接口和用戶線路接口（SLIC）設(shè)備。
The HD66773, controller driver LSI, displays 132RGB-by-176 dot graphics on TFT displays in 260,000
colors. The HD66773’s bit-operation functions, 18-bit high-speed bus interface, and high-speed RAMwrite
functions enable efficient data transfer and high-speed rewriting of data to the graphic RAM.
YSS915 (KP2V2) is an LSI for processing Karaoke voice signals.
This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and
key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI
chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that
YSS915 is applicable to various uses.
In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the
surround effect is applied to the movie and music sources for giving the users more enjoyment.
YSS915 is pin compatible with and register compatible with YSS903 (KP2V).
ST7529液晶驅(qū)動(dòng) The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
LCD Driver datasheet
The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of
supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source
driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of
SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power
consumption.
