Vector Floating-Point Unit Speeds ARM9

NXP’s 90-nm, 208-MHz LPC32x0 is based on ARM’s ARM926EJ-S core plus a vector floating-point (VFP) coprocessor. The chip has 256 kbytes of SRAM plus 32-kbyte instruction and data caches. It can handle off-chip SDR and DDR RAM, NAND flash, and an SD memory card interface. Peripherals include 10/100 Ethernet, full-speed USB OTG, a 24-bit LCD controller, and a threechannel, 10-bit analog-to-digital converter for touchscreen support, plus two SPI, two SSP, two I2C, two I2S, and seven serial ports. Pricing starts at $6.95.
