In addition to microcontrollers, several peripherals also exist that support the I2C bus. The memory map shows regions in the TPA specified by Interrupt vectors, BIOS and DOS Communications area, the IO. This is not true of the non-re-entrant code. Conditionally samples the keyboard in run time mode If exp <>0, return decimal value of last key struck and clear key register. (0 if no key struck ) If exp = 0, return a 1 if the last key struck has the same decimal value as the expression.

ARM and x86 are not processor architectures in the same way as, say, Intel's Sandy Bridge or AMD's Bobcat. Full-custom register files often start with a SRAM design. In this sequence register 2 was initialized to the starting data address and register 3 was initialized to indicate the first word address after the 10th data word to be cleared.

Each Navigator/Jade design includes User Blocks in the data flow path, ideal for inserting custom processing IP. Workspace The workspace is a set of 16 contiguous words of memory, the first of which is located by the workspace pointer. This article series walks through a few signal-analysis and -processing examples to introduce DSP concepts. It is the actual Cross Assembler program written in internal code, and it is suggested that it be assigned to a permanent disk file.

Steps such as load the accumulator (LDA), add to the accumulator (ADD), and store the accumulator (STA) were common in programs written for such machines. (The instruction mnemonics used here are simply illustrative and are not intended to be identified with any specific computer or microprocessor.) But there was a fundamental limitation— the bottleneck effect of forcing all transactions to be performed via a single accumulator (Figure 1-12).

Each separate form factor requires a specific interface for the chip to connect to called a socket. I find it interesting that the LEGO Mindstorms NXT set has a microprocessor [32-bit AT91SAM7S256 (ARM7TDMI) main microprocessor @ 48 MHz (256 KB flash memory, 64 KB RAM)] for doing the thinking, and a microcontroller [8-bit ATmega48 microcontroller @ 4 MHz (4 KB flash memory, 512 Bytes RAM)] for interfacing with the sensors and motors. PicoTurbo maintains that its cores do not infringe on ARM's patents because they are based on an independently designed "clean room" microarchitecture. [April 17, 2000] Figure 1: Block diagram of the picoTurbo pT-110.

Their engineers made their pitch and we made ours. Interrupt Requiring Re-entrant Programming As an example of re-entrant coding, consider the problem of forming a starting and an ending address for a block of data to be operated on by a subroutine. Data is directly loaded in sequence into the RAM through P24 (MSB)-P31 (LSB). INT4 executes a context switch and finds its new workspace pointer is FF8C 16 and its new PC is FFAC 16. Different instruction execution times (in cycles) make it difficult to compare systems based purely on clock speed or number of cycles per second.
