The CSG 65CE02 is an 8/16-bit microprocessor developed by Commodore Semiconductor Group in 1988. [1] It is a member of the MOS Technology 6502 family, developed from the CMOS WDC 65C02 released by the Western Design Center in 1983.
Its instruction set is a superset of the 6502 microprocessor. [1] Incorporated into this particular IC are the following: [1] Enhanced 6502 processor; 24 digital I/O; 4 inputs to 8-bit analog-to-digital converters; Universal asynchronous receiver/transmitter (UART) High-speed interprocessor link; Power-down SLEEP mode; Extended memory addressing
The 6502 instruction set includes BRK (opcode $00), which is technically a software interrupt (similar in spirit to the SWI mnemonic of the Motorola 6800 and ARM processors). BRK is most often used to interrupt program execution and start a machine language monitor for testing and debugging during software development.
SSE4 (Streaming SIMD Extensions 4) is a SIMD CPU instruction set used in the Intel Core microarchitecture and AMD K10 (K8L).It was announced on September 27, 2006, at the Fall 2006 Intel Developer Forum, with vague details in a white paper; [1] more precise details of 47 instructions became available at the Spring 2007 Intel Developer Forum in Beijing, in the presentation. [2]
The processor completes the current instruction but does not change the registers or memory in any way—the computational results of the completed instruction are discarded. An abort interrupt does not literally abort an instruction. [2] The program bank (PB, see above) is pushed to the stack.
In the original SSE instruction set, conversion to and from integers placed the integer data in the 64-bit MMX registers. SSE2 enables the programmer to perform SIMD math on any data type (from 8-bit integer to 64-bit float) entirely with the XMM vector-register file, without the need to use the legacy MMX or FPU registers.
While what these instructions do is similar to bit level gather-scatter SIMD instructions, PDEP and PEXT instructions (like the rest of the BMI instruction sets) operate on general-purpose registers. [12] The instructions are available in 32-bit and 64-bit versions. An example using arbitrary source and selector in 32-bit mode is:
The SSE2 also complements the floating-point vector operations of the SSE instruction set by adding support for the double precision data type. Other SSE2 extensions include a set of cache control instructions intended primarily to minimize cache pollution when processing infinite streams of information, and a sophisticated complement of ...
