Sun may not shine on UltraSparc IIe
Sun has released the embedded version of its 64-bit UltraSparc, the IIe. This integrated processor incorporates an execution unit based on Sun's Sparc V9 architecture that incorporates a floating-point unit and VIS (visual-instruction-set) multimedia extensions; a unified, four-way-set-associative, 256-kbyte integrated L2 cache; a 32-bit, 66-MHz PCI-bus controller; and a PC-100 SDRAM controller with ECC. The 16-kbyte L1 instruction cache is two-way-set-associative, and the 16-kbyte data cache is direct-mapped. The execution unit has a four-way, superscalar pipeline with six pipes (two integer, two floating-point/graphics, one load/store, and one branch). Maximum power dissipation is 13W at 500 MHz with a 1.7V core voltage. Sun has packaged the UltraSparc IIe in a low-cost, 370-pin ceramic PGA. The UltraSparc IIe is available now in 500- and 400-MHz versions for $225 and $145 (50,000), respectively.
