High-Performance Computing.
The high-performance numerical computing work I did at Apple, Sky Computers, and EADS is sometimes called supercomputing. High-performance computing is abbreviated HPC. It involves digital signal processing (DSP), optimization, designing optimized routines, math, and assembly language. I worked at Sky Computers, but Mercury Computer Systems does similar work.
The PowerPC architecture from IBM and Freescale (formerly Motorola) describes a scalar instruction set. AltiVec Technology is an additional feature that provides vector instructions, also described as single-instruction multiple-data (SIMD). This is one type of parallel computing because four sets of data are operated on in parallel by one instruction. Velocity Engine is Apple's name for AltiVec, and VMX is IBM's name. (We can thank the lawyers and trademark issues for that.) Apple's G4 and G5 systems use various AltiVec CPUs. I worked directly on 604e, 7400, 7410, and 970 CPUs. The 7447 and 7450 are similar. The Cell processor shares some features with PowerPC and AltiVec.
SIMD and Intel's SSE.
Since Apple switched to Intel processors, I have worked with Intel's SIMD technologies, SSE, SSE2, and SSE3, which use the MMX and XMM registers in IA-32 CPUs. SSE is similar to AltiVec. I have used by IA-32 and EM64T, also known as x86 and x86-64.
Vector Processing.
Vector processing refers to calculations involving arrays of numbers. The most common examples are digital signal processing and image processing, in which arrays contain information about audio, visual, radar, or other signals. Routines I wrote include the Fast Fourier Transform (FFT); finite impulse response (FIR) filters; infinite impulse response filters (IIR); sine, cosine, tangent, logarithm, and exponential routines; and an Advanced Encryption Standard (AES) routine.
Operating Systems and Embedded Systems.
At Digital Equipment Corporation, I worked in operating systems groups for many years, mostly in the kernel. Embedded systems work is like operating systems work in miniature, so all of my operating system experience is relevant to embedded system work.
What we call a resume or résumé in the United States is typically called a curriculum vitae or CV in Europe.
