LM1894MX 描述
The AT40KAL can be used as a coprocessor for high-speed (DSP/processor-based) designs by implementing a variety of computation intensive, arithmetic functions. These include adaptive finite impulse response (FIR) filters, fast Fourier transforms (FFT), con- volvers, interpolators and discrete-cosine transforms (DCT) that are required for video compression and decompression, encryption, convolution and other multimedia applications.
LM1894MX 特点
LM1894MXhe IMSs continuously compute the target bit plane (u, v) or bit space addresses (u, v, w) in typical line-by-line, raster- scan serial sequence. For each output pixel address, they compute the corresponding remapped source image coordi- nates, each of whose upper 24 bits become the source bit plane addresses (x, y). An additional lower twelve bits are available through the target address port in the optional extended address mode. Source image addresses may be generated at up to 40MHz, with the corresponding target image addresses then appearing at up to (40/k)MHz, where k is the size of the interpolation kernel implemented. In the two-IMS system, one LM1894MX computes the horizontal coordinates x and u while the other generates the y and v
LM1894MX 应用
Honeywells enhanced SOI RICMOS™ IV (Radiation Insen- sitive CMOS) technology is radiation hardened through the use of advanced and proprietary design, layout and pro- cess hardening techniques. The RICMOS™ IV process is a 5-volt, SIMOX CMOS technology with a 150 Å gate oxide and a minimum drawn feature size of 0.75 µm (0.6 µm effective gate lengthLeff). Additional features include tungsten via plugs, Honeywells proprietary SHARP pla- narization process, and a lightly doped drain (LDD) struc- ture for improved short channel reliability. A 7 transistor (7T) memory cell is used for superior single event upset hardening, while three layer metal power bussing and the low collection volume SIMOX substrate provide improved dose rate hardening.
